Abstract:

In a proxy blind signature scheme, the proxy can blindly sign the file for the delegated signer. In the paper, we propose a new proxy blind signature scheme, which resolves two issues in the Tan’s proxy blind signature scheme: ⑴Security, both original signer and signature receiver can forge a valid proxy blind signature for any file. ⑵Traceability, the proxy signer can relate the process of the proxy blind signature to the unblind signature for the file.

Key words: Proxy signature, Blind signature, Proxy blind signature;
