Proxy signature information generated in the present application shows a signature of the original signer and also shows a signature of a proxy signer. Once a proxy signature is created, the proxy signature cannot be repudiated by the proxy signer, and has strong non-repudiation and strong unforgeability. The proxy signature method has the advantage of resisting quantum computer attack.
