ID-Based Proxy Signature Scheme with Efficient Proxy Revocation

The proxy revocation is very significant in the proxy signature system,and SONG et al once proposed a proxy signature scheme with proxy revocation. In this paper,a new ID-Based proxy signature scheme with proxy revocation is presented. In this scheme,once the malicious proxy signer is found,the original signer can immediately revoke the signing power of the malicious proxy signer through the trusted authority. And with user's personal information as the ID identification, the cost of key storage and management is greatly reduced.
