A Secure Proxy Blind Signature Scheme Based on ECDLP

摘要：

To overcome the secure weakness of the existing proxy blind signature scheme based on ECDLP, an improved scheme is presented. The security of the improved scheme is enhanced by improving on the generate form of the proxy commission and the proxy private key in the proxy phase, the procedure of blinding and unblinding, and the corresponding verification equation of proxy blind signature. The analysis shows that the new scheme resolves secure problems in the former schemes, meets the seven aspects of security features needed by proxy blind signature scheme. The analytic results prove that the new scheme is more secure and practicable.
