摘要
分析了现有批验证签名方案秘密信息泄漏、签名伪造等安全漏洞以及协议过程复杂、签名认证运算开销大等不足之处。基于超椭圆曲线密码提出了一类批验证签名方案,该方案由交互式与非交互式批验证签名协议组成;方案充分发挥了超椭圆曲线密码系统密钥量小、效率高的优势,其协议与算法安全、简洁、高效,降低了软硬件实现的系统开销,可广泛应用于计算机与无线通信等网络环境。
Analyses are made on the security threats of present batch verification signature schemes,and an improved batch verification signature scheme based on hyper-elliptic curves cryptosystem that can gain a wide application in computer and wireless communication network is presented.The probabilistic encryption algorithm in the scheme avoids the relevance between different signatures generated by the same signer.The independence of signature security on the hypothesis of an absolutely trustable party in the scheme prevents coalition attack and generalized signature forgery.Further details analyses also justify its brevity,security, high efficiency,and thus considerable improvement on system overheads regarding software and hardware application.
