"What Is Post-Quantum Cryptography?"

Researchers and security firms are working to develop new cryptographic algorithms that can resist future quantum attacks launched by hackers as quantum computers are expected to render currently used encryption algorithms obsolete. The breaking of current encryption algorithms by quantum computers poses a significant threat to the privacy of sensitive data used in the processes of autonomous vehicles, military hardware, online financial transactions, and more. This article continues to discuss the two main types of digital encryption, why quantum computers pose a threat to current cryptographic defenses, whether such will breach these defenses soon, the impact that quantum attacks could have if quantum-safe cryptographic defenses are not implemented, as well as the concept of post-quantum cryptography and the possible approaches to defending against quantum attacks.
