BLS Signature Scheme
Zhenfei Zhang, Dan Boneh, Hoeteck Wee, Sergey V Gorbunov · 2019
The BLS signature scheme was introduced by Boneh-Lynn-Shacham in 2001. The signature scheme relies on pairing-friendly curves and supports non-interactive aggregation properties. That is, given a collection of signatures (sigma_1, ..., sigma_n), anyone can produce a short signature (sigma) that authenticates the entire collection. BLS signature scheme is simple, efficient and can be used in a variety of network protocols and systems to compress signatures or certificate chains. This document specifies the BLS signature and the aggregation algorithms.
