Abstract

BLS signature is an elliptic curve cryptography with an attractive feature that signatures can be aggregated and shortened. We have designed two ASIC architectures for hashing to the elliptic curve and pair-ing to minimize the latency. Also, the designs are optimized for BLS12-381, a new and safe curve.
