摘　　要：为了解决电力调度系统的安全性问题,克服传统公钥密码体制证书管理复杂的缺陷,在无双线性对思想的基础上,构造了一种基于DSA的无证书数字签名方案。方案利用零知识方式对调度用户身份进行认证,将签名身份与公钥进行哈希处理,防止身份替换攻击。利用离散对数难题,由调度中心和调度用户共同产生的私钥对和公钥对,减少了存储空间,降低了计算开销。与同类算法相比,签名方案具有消息的完整性、抗否认性、抗伪造型、签名的可验证性等特点。应用测试表明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 and the drawbacks of complex certificate management that caused by traditional public key cryptography, the certificateless signature scheme with DSA and no pairing based on electrical dispatching system is put forward. Dispatching users are authenticated by means of zero-knowledge, the identification of signature and public key have been processed by Hash, to avoid the attack of identification switch. The private key pair and public key pair co-produced by the dispatching center and dispatching users, using the discrete logarithm problem, save storage space, and reduce the computational complexity. Compared with similar algorithm, it is characterized with integrity, anti-denying, anti-forgery, verification of signature. The application test shows that the algorithm will meet the requirement of real-time for electrical dispatching system.
