摘　　要：为了克服传统算法效率低、安全性差的弊端,防止电子选举系统操作人员出现失误,确保选举结果准确无误,提高选举系统的可靠性,提出了一种基于SM2椭圆曲线公钥密码算法和改进的SM3密码杂凑算法实现选举数据完整性验证的方法。解决方案首先利用SM2椭圆曲线公钥密码算法生成选举数据的"数字签名",然后利用SM3密码杂凑算法对前后台获取的数据进行哈希运算并对比生成的哈希值,从而实现选举数据的一致性验证。实验结果表明,相对于消息摘要MD5等传统算法,SM3杂凑算法具有更高的安全性;相对于安全散列SHA-256等算法,SM3杂凑算法的速度更快。解决方案在保证高效运行速度的基础上更安全地实现了选举系统数据的一致性验证。In order to improve low efficiency and poor security of traditional algorithms, prevent the mistakes from the staff, ensure the accuracy of the election results and improve the reliability of the electronic election system, a solution based on public key cryptographic algorithm SM2 and improved cryptographical hash algorithm SM3 was proposed to verify the consistency of election data. Firstly, the public key cryptographic algorithm SM2 was used to generate digital signature for election data, and then the data was processed by SM3 cryptographical hash algorithm. At last the value of election data was compared to verify the consistency of the ballot. Experiments show that cryptographical hash algorithm SM3 has higher security than message digest algorithm MD5, and is faster than secure hash algorithm SHA-256. The consistency verification of the election system was implemented by SM3 faster and safer.
