High Speed ASIC Architectures for Aggregate Signature over BLS12-381
Kaoru MASADA, Ryohei NAKAYAMA, Makoto Ikeda · IEICE Transactions on Electronics · 2022
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 pairing to minimize the latency. Also, the designs are optimized for BLS12-381, a relatively new and safe curve.
