对一个高效的基于身份的代理盲签名方案的分析和改进
Analysis and Improvement of an Efficient ID-Based Proxy Blind Signature Scheme
摘要
Abstract
The paper analyzes the security of the identity-based proxy blind signature scheme with untrusted Private Key Generation (PKG) proposed by the scholar Nongqiang and points out that the scheme does not satisfy the property of unforgeability and there exist some security drawbacks such as proxy signer stealing the private of original signer and common user forging signature. Aiming at the existing problems of the scheme, a novel proxy blind signature scheme with untrusted PKG is proposed, and its correctness and security are analyzed关键词
