摘　　要：针对RSA数字签名在电力调度系统应用时执行速度慢和数据存储量大的局限性,设计基于电力调度系统的ECC有序多重数字签名方案.设计方案将调度签名者的身份与调度文件进行哈希函数处理,防止身份替换攻击,保证了消息的完整性;数字签名过程避开逆运算,能够降低时间复杂度;每个调度签名者签名的结果回送给签名中心,防止联合欺骗,保证了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:该方案签名及验证过程消耗的时间较短,而且具有较小的通信量,能够满足电力调度的实时性要求.The ECC sequential multiple digital signature scheme is designed based on electrical dispatching system,in view of the limitation of low execution speed and great size of memory of RSA in electrical dispatching system.The scheme will process the identity of signer and the dispatching documents by hash function,avoid the attack of alternative identity and ensure the integrity of information;the digital signature process avoids the inverse operation,and lowers the complication of time;the signing result of each dispatching signer will be sent to the signature center,avoid joint cheating and ensure the verifiability of valid ticket,and the security of electrical dispatching system is then solved.The application test indicates that the duration of signature and verification of the scheme is short,with relatively small communication and the requirement of real-time for power dispatching is satisfied.
