ePrint Report: On the Security of Blind Signatures in the Multi-Signer Setting

Samuel Bedassa Alemu, Julia Kastner

Blind signatures were originally introduced by Chaum (CRYPTO ’82) in the context of privacy-preserving electronic payment systems. Nowadays, the cryptographic primitive has also found applications in anonymous credentials and voting systems. However, many practical blind signature schemes have only been analysed in the game-based setting where a single signer is present. This is somewhat unsatisfactory as blind signatures are intended to be deployed …
