A Proxy Blind Signature Scheme with Proxy Revocation

摘要

A proxy blind signature allows the designated proxy signer using the proxy private key to generate a blind signature on behalf of the original signer.In previous proxy blind signature schemes,there was no revocation protocol wherein the original signer could delegate his signing capability to a proxy signer In this paper,we propose a proxy blind signature scheme with the proxy revocation,where the original signer can revoke his delegation to a proxy signer whenever he wants.Moreover,the proposed scheme satisfies all security properties for the proxy blind signature.
