Abstract

Abstract

Identifiability is one of several security requirements of general proxy signature schemes, i.e. a verifier can determine the identity of the corresponding proxy signer from a proxy signature. In special application, the original signer wants to conceal the identity of the corresponding proxy signer in the proxy signature. The verifier can not recognize the identity of the proxy signer from the proxy signature. In the case of a later dispute, the verifier can reveal the real identity of the proxy signer with the help of the original signer from the proxy signature. In the paper, a new proxy signature scheme should satisfy this requirement.
