The use of encryption for medical images offers several benefits. Firstly, it enhances the confidentiality and privacy of patient data, preventing unauthorized individuals or entities from accessing sensitive medical information. Secondly, encrypted medical images may be sent securely via unreliable networks, like the Internet, without running the danger of data eavesdropping or tampering. Traditional methods of storing and retrieving medical images often lack efficient encryption and privacy-preserving mechanisms. This project delves into enhancing the security and accessibility of medical image storage across diverse cloud environments. Through the implementation of encryption methods, pixel scrambling techniques, and integration with AWS S3, the research aimed to fortify the confidentiality of medical images while ensuring rapid retrieval. These findings collectively illuminate the security, and operational efficiency of the implemented encryption, scrambling techniques, AWS integration, and offer a foundation for advancing secure medical image retrieval in multi-cloud settings.

Data security in numerous businesses, including banking, healthcare, and transportation, depends on cryptography. As IoT and AI applications proliferate, this is becoming more and more evident. Despite the benefits and drawbacks of traditional cryptographic methods such as symmetric and asymmetric encryption, there remains a demand for enhanced security that does not compromise efficiency. This work introduces a novel approach called Multi-fused cryptography, which combines the benefits of distinct cryptographic methods in order to overcome their shortcomings. Through a comparative performance analysis; our study demonstrates that the proposed technique successfully enhances data security during network transmission.

Searchable encryption allows users to perform search operations on encrypted data before decrypting it first. Secret sharing is one of the most important cryptographic primitives used to design an information theoretic scheme. Nowadays cryptosys-tem designers are providing a facility to adjust the security parameters in real time to circumvent AI-enabled cyber security threats. For long term security of data which is used by various applications, proactive secret sharing allows the shares of the original secret to be dynamically adjusted during a specific interval of time. In proactive secret sharing, the updation of shares at regular intervals of time is done by the servers (participants) and not by the dealer. In this paper, we propose a novel proactive secret sharing scheme where the shares stored at servers are updated using preshared pairwise keys between servers at regular intervals of time. The direct search of words over sentences using the conjunctive search function without the generation of any index is possible using the underlying querying method.

Data in AI-Empowered Electric Vehicles is protected by using blockchain technology for immutable and verifiable transactions, in addition to high-strength encryption methods and digital signatures. This research paper compares and evaluates the security mechanisms for V2X communication in AI-enabled EVs. The purpose of the study is to ensure the reliability of security measures by evaluating performance metrics including false positive rate, false negative rate, detection accuracy, processing time, communication latency, computational resources, key generation time, and throughput. A comprehensive experimental approach is implemented using a diverse dataset gathered from actual V2X communication condition. The evaluation reveals that the security mechanisms perform inconsistently. Message integrity verification obtains the highest detection accuracy with a low false positive rate of 2\% and a 0\% false negative rate. Traffic encryption has a low processing time, requiring only 10 milliseconds for encryption and decryption, and adds only 5 bytes of communication latency to V2X messages. The detection accuracy of intrusion detection systems is adequate at 95\%, but they require more computational resources, consuming 80\% of the CPU and 150 MB of memory. In particular attack scenarios, certificate-based authentication and secure key exchange show promise. Certificate-based authentication mitigates MitM attacks with a false positive rate of 3\% and a false negative rate of 1\%. Secure key exchange thwarts replication attacks with a false positive rate of 0 and a false negative rate of 2. Nevertheless, their efficacy varies based on the attack scenario, highlighting the need for adaptive security mechanisms. The evaluated security mechanisms exhibit varying rates of throughput. Message integrity verification and traffic encryption accomplish high throughput, enabling 1 Mbps and 800 Kbps, respectively, of secure data transfer rates. Overall, the results contribute to the comprehension of V2X communication security challenges in AI-enabled EVs. Message integrity verification and traffic encryption have emerged as effective mechanisms that provide robust security with high performance. The study provides insight for designing secure and dependable V2X communication systems. Future research should concentrate on enhancing V2X communication s security mechanisms and exploring novel approaches to resolve emerging threats.

The HTTP protocol is the backbone for how traffic is communicated over the Internet and between web applications and users. Introduced in 1997 with HTTP 1.0 and 1.1, HTTP has gone through several developmental changes throughout the years. HTTP/1.1 suffers from several issues. Namely only allowing a one-to-one connection. HTTP/2 allowed for multiplexed connections. Additionally, HTTP/2 attempted to address the security issues that were faced by the prior version of HTTP by allowing administrators to enable HTTPS, as well as enable certificates to help ensure the encryption and protection of data between users and the web application. One of the major issues HTTP/2 faces is that it allows users to have multiplexed connections, but when there is an error and data needs to be retransmitted, this leads to head of line blocking. HTTP/3 is a new protocol that was proposed for formalization to the IETF in June of 2022. One of the first major changes is that unlike prior versions of HTTP that used the TCP/IP method of networking for data transmission, HTTP/3 uses UDP for data transmission. Prior research has focused on the protocol itself or investigating how certain types of attacks affect your web architecture that uses QUIC and HTTP/3. One area lacking research in this topic is how to secure web architecture in the cloud that uses this new protocol. To this end, we will be investigating how logging can be used to secure your web architecture and this protocol in the cloud.

The world has seen a quick transition from hard devices for local storage to massive virtual data centers, all possible because of cloud storage technology. Businesses have grown to be scalable, meeting consumer demands on every turn. Cloud computing has transforming the way we do business making IT more efficient and cost effective that leads to new types of cybercrimes. Securing the data in cloud is a challenging task. Cloud security is a mixture of art and science. Art is to create your own technique and technologies in such a way that the user should be authenticated. Science is because you have to come up with ways of securing your application. Data security refers to a broad set of policies, technologies and controls deployed to protect data application and the associated infrastructure of cloud computing. It ensures that the data has not been accessed by any unauthorized person. Cloud storage systems are considered to be a network of distributed data centers which typically uses cloud computing technologies like virtualization and offers some kind of interface for storing data. Virtualization is the process of grouping the physical storage from multiple network storage devices so that it looks like a single storage device.Storing the important data in the cloud has become an essential argument in the computer territory. The cloud enables the user to store the data efficiently and access the data securely. It avoids the basic expenditure on hardware, software and maintenance. Protecting the cloud data has become one of the burdensome tasks in today’s environment. Our proposed scheme "Certificateless Compressed Data Sharing in Cloud through Partial Decryption" (CCDSPD) makes use of Shared Secret Session (3S) key for encryption and double decryption process to secure the information in the cloud. CC does not use pairing concept to solve the key escrow problem. Our scheme provides an efficient secure way of sharing data to the cloud and reduces the time consumption nearly by 50 percent as compared to the existing mCL-PKE scheme in encryption and decryption process.Distributed Cloud Environment (DCE) has the ability to store the da-ta and share it with others. One of the main issues arises during this is, how safe the data in the cloud while storing and sharing. Therefore, the communication media should be safe from any intruders residing between the two entities. What if the key generator compromises with intruders and shares the keys used for both communication and data? Therefore, the proposed system makes use of the Station-to-Station (STS) protocol to make the channel safer. The concept of encrypting the secret key confuses the intruders. Duplicate File Detector (DFD) checks for any existence of the same file before uploading. The scheduler as-signs the work of generating keys to the key manager who has less task to complete or free of any task. By these techniques, the proposed system makes time-efficient, cost-efficient, and resource efficient compared to the existing system. The performance is analysed in terms of time, cost and resources. It is necessary to safeguard the communication channel between the entities before sharing the data. In this process of sharing, what if the key manager’s compromises with intruders and reveal the information of the user’s key that is used for encryption. The process of securing the key by using the user’s phrase is the key concept used in the proposed system "Secure Storing and Sharing of Data in Cloud Environment using User Phrase" (S3DCE). It does not rely on any key managers to generate the key instead the user himself generates the key. In order to provide double security, the encryption key is also encrypted by the public key derived from the user’s phrase. S3DCE guarantees privacy, confidentiality and integrity of the user data while storing and sharing. The proposed method S3DCE is more efficient in terms of time, cost and resource utilization compared to the existing algorithm DaSCE (Data Security for Cloud Environment with Semi Trusted Third Party) and DACESM (Data Security for Cloud Environment with Scheduled Key Managers).For a cloud to be secure, all of the participating entities must be secure. The security of the assets does not solely depend on an individual s security measures. The neighbouring entities may provide an opportunity to an attacker to bypass the user s defences. The data may compromise due to attacks by other users and nodes within the cloud. Therefore, high security measures are required to protect data within the cloud. Cloudsim allows to create a network that contains a set of Intelligent Sense Point (ISP) spread across an area. Each ISPs will have its own unique position and will be different from other ISPs. Cloud is a cost-efficient solution for the distribution of data but has the challenge of a data breach. The data can be compromised of attacks of ISPs. Therefore, in OSNQSC (Optimized Selection of Nodes for Enhanced in Cloud Environment), an optimized method is proposed to find the best ISPs to place the data fragments that considers the channel quality, distance and the remaining energy of the ISPs. The fragments are encrypted before storing. OSNQSC is more efficient in terms of total upload time, total download time, throughput, storage and memory consumption of the node with the existing Betweenness centrality, Eccentricity and Closeness centrality methods of DROPS (Division and Replication of Data in the Cloud for Optimal Performance and Security).

Finally, we recommend control mechanisms to improve blockchain security in the cloud environment. The paper results show that AES algorithms can be used in blockchain smart contracts to enhance security, privacy, and integrity to ensure secure data in transit and at rest.

Cloud computing is a nascent paradigm in the field of data technology and computer science which is predicated on the use of the Internet, often known as the World Wide Web. One of the prominent concerns within this field is the security aspects of cloud computing. Contrarily, ensuring the preservation of access to the protection of sensitive and confidential information inside financial organizations, banks and other pertinent enterprises holds significant significance. This holds significant relevance. The efficacy of the security measures in providing assurance is not infallible and can be compromised by malevolent entities.

Time delay averagely approximates improvement 6-7\%, storage 10-12\% and security 8-10\%.

The enhancement of big data security in cloud computing has become inevitable dues to factors such as the volume, velocity, veracity, Value, and velocity of the big data. These enhancements of big data and cloud technologies have computing enabled a wide range of vulnerabilities in applications in organizational business environments leading to various attacks such as denial-of-service attacks, injection attacks, and Phishing among others. Deploying big data in cloud computing environments is a rapidly growing technology that significantly impacts organizations and provides benefits such as demand-driven access to computational services, a distorted version of infinite computing capacity, and assistance with demand-driven scaling up, scaling down, and scaling out.

The novelty contribution of the paper is threefold: First, explore the current challenges and vulnerabilities in securing big data in cloud computing and how the RSA algorithm can be used to address them. Secondly, we implement the RSA algorithm in a cloud computing environment using the AWS cloud platform to secure big data to improve the performance and scalability of the RSA algorithm for big data security in cloud computing. We compare the RSA algorithm to other cryptographic algorithms in terms of its ability to enhance big data security in cloud computing. Finally, we recommend control mechanisms to improve security in the cloud platform. The results show that the RSA algorithm can be used to improve Cloud Security in a network environment.

Aiming at the security issues such as data leakage and tampering faced by experimental data sharing, research is conducted on data security sharing under multiple security mechanisms such as mixed encryption and secure storage on the blockchain against leakage, as well as experimental data tampering identification and recovery strategies based on an improved practical Byzantine fault-tolerant (PBFT) consensus algorithm. An integrated scheme for secure storage, sharing, and tamper resistant recovery of test data is proposed to address the contradiction between the security and sharing of sensitive data. Provide support for the security application of blockchain in experimental data management.

With increased connectivity and the application of intelligent technologies, intelligent and connected vehicles are evolving rapidly, which offers new opportunities for vehicle data security risks. However, there are currently insufficient studies to comprehensively map the security risks throughout the life cycle of intelligent and connected vehicle data. The object of this paper is to identify the main data security risks at different data life cycle phases in the field of intelligent and connected vehicles, and the data security problems those risks may bring.

Therefore, it is verified that the information encryption security system using chaos algorithm has high security.

The role of information security in network accounting is very important, but there is a problem of inaccurate outcome evaluation. The one-way hash encryption algorithm cannot solve the information security problem in network accounting, and the evaluation is unreasonable.

MBAZ shows that under certain evaluation criteria, the AES algorithm is safe for the accounting information of network accounting the accuracy and time are better than the one-way hash encryption algorithm.

The globe is observing the emergence of the Internet of Things more prominently recognized as IoT. In this day and age, there exist numerous technological apparatuses that possess the capability to be interconnected with the internet and can amass, convey, and receive information concerning the users. This technology endeavors to simplify existence, however, when the users information is the central concern for IoT operation, it is necessary to adhere to security measures to guarantee privacy and prevent the exploitation of said information. The customary cryptographic algorithms, such as RSA, AES, and DES, may perform adequately with older technologies such as conventional computers or laptops. Nevertheless, contemporary technologies are heading towards quantum computing, and this latter form possesses a processing capability that can effortlessly jeopardize the aforementioned cryptographic algorithms. Therefore, there arises an imperative necessity for a novel and resilient cryptographic algorithm. To put it differently, there is a requirement to devise a fresh algorithm, impervious to quantum computing, that can shield the information from assaults perpetrated utilizing quantum computing. IoT is one of the domains that must ensure the security of the information against malevolent activities. Besides the conventional cryptography that enciphers information into bits, quantum encryption utilizes qubits, specifically photons and photon polarization, to encode data.

The security of our data is the prime priority as it is said “Data is the new Oil”. Nowadays, most of our communications are either recorded or forged. There are algorithms used under classical encryption, such as Rivest-Shamir-Adleman (RSA), digital signature, elliptic-curve cryptography (ECC), and more, to protect our communication and data. However, these algorithms are breakable with the help of Quantum Cryptography. In addition, this technology provides the most secure form of communication between entities under the fundamental law of Physics. Here, we are abiding to discuss the term “Quantum Cryptography.” The aim of this paper is to explore the knowledge related to the Quantum Cryptography, Quantum Key Distribution; and their elements, implementation, and the latest research. Moreover, exploration of the loopholes and the security of Internet of Things (IoT) infrastructure and current used classical cryptographic algorithms are described in the paper.

Quantum Cryptography looks promising to provide a new level of secure communication by applying quantum mechanics concepts to cryptography. The research in the domain emphasizes that such systems can detect eavesdropping and ensure that it does not occur at all. This paper reviews the existing state of quantum cryptography, which includes an introduction to quantum computing and quantum key distribution algorithm, special attention is given to the implementation and working of the BB84 Protocol. It also provides a glimpse of post-quantum cryptography.

Encryption defined as change information process (which called plaintext) into an unreadable secret format (which called ciphertext). This ciphertext could not be easily understood by somebody except authorized parson. Decryption is the process to converting ciphertext back into plaintext. Deoxyribonucleic Acid (DNA) based information ciphering techniques recently used in large number of encryption algorithms. DNA used as data carrier and the modern biological technology is used as implementation tool. New encryption algorithm based on DNA is proposed in this paper. The suggested approach consists of three steps (conventional, stream cipher and DNA) to get high security levels. The character was replaced by shifting depend character location in conventional step, convert to ASCII and AddRoundKey was used in stream cipher step. The result from second step converted to DNA then applying AddRoundKey with DNA key. The evaluation performance results proved that the proposed algorithm cipher the important data with high security levels.

Securing communication and information is known as cryptography. To convert messages from plain text to cipher text and the other way around. It is the process of protecting the data and sending it to the right audience so they can understand and process it. Hence, unauthorized access is avoided. This work suggests leveraging DNA technology for encrypt and decrypt the data. The main aim of utilizing the AES in this stage will transform ASCII code to hexadecimal to binary coded form and generate DNA. The message is encrypted with a random key. Shared key used for encrypt and decrypt the data. The encrypted data will be disguised as an image using steganography. To protect our data from hijackers, assailants, and muggers, it is frequently employed in institutions, banking, etc.

The problem of information privacy has grown more significant in terms of data storage and communication in the 21st century due to the technological explosion during which information has become a highly important strategic resource. The idea of employing DNA cryptography has been highlighted as a potential technology that offers fresh hope for unbreakable algorithms since standard cryptosystems are becoming susceptible to assaults. Due to biological DNA s outstanding energy efficiency, enormous storage capacity, and extensive parallelism, a new branch of cryptography based on DNA computing is developing. There is still more study to be done since this discipline is still in its infancy. This work proposes a DNA encryption strategy based on cryptographic key generation techniques and chaotic diffusion operation.

A hybrid cryptosystem is developed in the paper “Hybrid Data Encryption and Decryption Using Hybrid RSA and DNA” by combining the advantages of asymmetric-key (public-key) and symmetric-key (private-key) cryptosystems. These two types of cryptosystems use a variety of key types. The approach addresses worries about the users right to privacy, authentication, and accuracy by using a data encryption procedure that is secure both ways. Data encoding and data decryption are two separate security techniques used by the system. It has been suggested that a hybrid encryption algorithm be used for file encryption to handle the issues with efficiency and security. RSA and DNA are combined in this method. The outcome so the tests show that the RSA and DNA hybrid encryption algorithms are suitable for use. In this particular study effort, the hybrid encryption and decoding for cloud processing with IOT devices used the DNA and RSA algorithms.

Information exchange occurs all the time in today’s internet era. Some of the data are public, and some are private. Asymmetric cryptography plays a critical role in securing private data transfer. However, technological advances caused private data at risk due to the presence of quantum computers. Therefore, we need a new method for securing private data. This paper proposes combining DNA cryptography methods based on the NTRU cryptosystem to enhance security data confidentiality. This method is compared with conventional public key cryptography methods. The comparison shows that the proposed method has a slow encryption and decryption time compared to other methods except for RSA. However, the key generation time of the proposed method is much faster than other methods tested except for ECC. The proposed method is superior in key generation time and considerably different from other tested methods. Meanwhile, the encryption and decryption time is slower than other methods besides RSA. The test results can get different results based on the programming language used.

E-health, smart health and telemedicine are examples of sophisticated healthcare systems. For end-to-end communication, these systems rely on digital medical information. Although this digitizing saves much time, it is open source. As a result, hackers could potentially manipulate the digital medical image as it is being transmitted. It is harder to diagnose an actual disease from a modified digital medical image in medical diagnostics. As a result, ensuring the security and confidentiality of clinical images, as well as reducing the computing time of encryption algorithms, appear to be critical problems for research groups. Conventional approaches are insufficient to ensure high-level medical image security. So this review paper focuses on depicting advanced methods like DNA cryptography and Chaotic Map as advanced techniques that could potentially help in encrypting the digital image at an effective level. This review acknowledges the key accomplishments expressed in the encrypting measures and their success indicators of qualitative and quantitative measurement. This research study also explores the key findings and reasons for finding the lessons learned as a roadmap for impending findings.
