ID-Based Proxy Blind Signature Scheme with Proxy Revocation

As existing id-based proxy blind signature scheme exist a common problem that the original signer can not revoke his delegation to a proxy signer whenever he wants. Combined with proxy signature and blind signature, the paper used bilinear map to construct an id-based proxy blind signature scheme with proxy revocation. It realizes the delegation revoke timely and overcome the problem that delegation can not be revoked in the current scheme. At the same time, the previous proxy blind signature can be validated after the proxy was revoked. It maintains the rights of original signer and proxy signer. Through analysis, the scheme is safe and efficient.
