Ring-Learning-with-Errors (RLWE) has emerged as the foundation of many
important techniques for improving security and privacy, including homomorphic
encryption and post-quantum cryptography. While promising, these techniques
have received limited use due to their extreme overheads of running on
general-purpose machines. In this paper, we present a novel vector Instruction
Set Architecture (ISA) and microarchitecture for accelerating the ring-based
computations of RLWE. The ISA, named B512, is developed to meet the needs of
ring processing workloads while balancing high-performance and general-purpose …
