Application of ECC sequential multiple signature scheme in electrical dispatching system

针对电力调度系统中的安全问题,设计基于电力调度系统的ECC(椭圆曲线密码)有序数字签名算法,利用零知识方式对信任中心认证,将签名身份与签名时效进行哈希处理,防止身份替换攻击,保证签名的完整性。与同类算法相比,该算法具有抗否认性、抗伪造性、签名整体的可验证性等特点,克服了消息采用明文传送带来的安全隐患,保证了消息的完整性和对合法操作票的可验证性,能够解决电力调度系统的安全性问题。应用测试表明该算法能够满足电力调度的实时性要求。

Targeting at the security problem of the electrical dispatching system, the ECC （Elliptic Curve Cryptography） Sequential Multiple Digital Signature Scheme based on electrical dispatching system is put forward. The confidence center is authenticated by means of zero-knowledge, the identification of signature and validity has been processed by Hash, to avoid the attack of identification switch and ensure the integrity of signature. Compared with similar algorithm, it is characterized with anti-denying, anti-forgery, verifiability of integrity of signature. It wilt avoid the security problem resulted from transferring message by plaintext, insure the integrity of massage and verifiability of legitimate operating tickets and solve the security problem of electrical dispatching system. The application test shows that the algorithm will meet the requirement of real-time for electrical dispatching system. ：
