摘要：

According to the problems of proxy revocation, original signer's forgery and proxy misuse in proxy signature, a secure proxy blind signature scheme with proxy revocation is proposed. In phase of signature, by embedding non-blind time-stamp in the Abe-Okamoto partially blind signature, the original signer can revoke delegation whenever necessary and all valid proxy signatures generated earlier can longer be verified. Besides having the basic properties of the proxy signature, the new scheme prevents proxy misuse, original signer's forgery and public key substitution attack.
