Abstract: The blind proxy signature scheme proposed in [1] is insecure. Managing center C cannot reveal the identity of the actual proxy signer of a given proxy signature. Besides，C and the original signer A can conspire to generate valid proxy signatures and impose them on an arbitrary proxy signer by using the identifying equation.
Key words: blind proxy signature, group signature.
