New ID-based Fair Blind Signatures

Authors: Girraj Kumar Verma


A blind signature is a cryptographic premitive in which a user can obtain a signature from the signer without revealing any information about message signature pair.Blind signatures are used in electronic payment systems, electronic voting machines etc.The anonymity can be misused by criminals by money laundering or by dubious money.To prevent these crimes, the idea of fair blind signature scheme was given by stadler et al.In fair blind signature scheme, there is a trusted third party judge who can provide a linking protocol to signer to link his view to the message signature pair.In this paper we are proposing some identity based fair blind signatures.
