This repository contains exploratory code implementing a Verifiably-Encrypted Signature Scheme.
It is an implementation of 4.4 described in Aggregate and Verifiably Encrypted Signatures from Bilinear Maps, on the BLS12-381 curve. It uses the guidelines proposed in On Cryptographic Protocols Employing Asymmetric Pairings – The Role Of ψ Revisited to adapt the scheme from a Type 2 pairing to a Type 3 (BLS12-381).
