A Low-Power BLS12-381 Pairing Crypto-Processor for Internet-of-Things Security Applications (2201.07496v1)
Published 19 Jan 2022 in cs.CR and cs.NI
Abstract: We present the first BLS12-381 elliptic curve pairing crypto-processor for Internet-of-Things (IoT) security applications. Efficient finite field arithmetic and algorithm-architecture co-optimizations together enable two orders of magnitude energy savings. We implement several countermeasures against timing and power side-channel attacks. Our crypto-processor is programmable to provide the flexibility to accelerate various elliptic curve and pairing-based protocols such as signature aggregation and functional encryption.
