ID-based designated -verifier proxy signature scheme without a trusted party

摘要：

As existing designated-verifier proxy signatures need to trust a Private Key Generator(PKG) unconditionally. Dishonest PKG can compute the private key of any user and forge a proxy signature of any one. In order to settle the problem who PKG causes, an ID-based designated -verifier proxy signature scheme without trusted PKG is proposed. The security analysis shows that ID-based designated-verifier proxy signature scheme without trusted PKG is secure and effective, The scheme is able to resist the forgery attack from PKG.
