"Low-Power Hardware Accelerator Offers Outsize Security"

A research team in the US has developed a novel hardware accelerator prototype for edge devices that can encrypt cloud-sent and -received messages with 1,000 to 6,000 times the energy efficiency of a standard RISC-V processor. Their proposed method is called RISE. Smartphones, Internet of Things (IoT) sensors, wearable devices, and other edge devices typically have limited computational capabilities and memory, requiring frequent data transmission to the cloud for processing. However, the data exchange between edge devices and the cloud poses security and privacy risks. Even if edge devices reserve additional computing power to encrypt data before sending it to the cloud, the data must often be decrypted in the cloud for processing. Homomorphic Encryption (HE), a cryptographic technique that enables encrypted data to be processed without first being decrypted, provides a solution to this security concern. RISE is a hardware accelerator designed to facilitate HE applications on edge devices. This article continues to discuss the RISE approach to homomorphic encryption.
