A Low-Power BLS12-381 Pairing Cryptoprocessor for Internet-of-Things Security Applications
Utsav Banerjee, Anantha P. Chandrakasan · IEEE Solid-State Circuits Letters · 2021
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.
