摘要
电子投票的安全性至关重要.文章创新性地将比特承诺技术运用于基于椭圆曲线的盲数字签名方案中,该方案的安全性基于椭圆曲线离散对数困难问题,有很强的安全性,且在密钥长度和执行效率上具有显著优势.并将该方案用于电子投票协议中,对协议的安全性进行了分析,有很强的实用价值.
The security of E-voting is essential. The bit commitment is innovatively used to the blind digital signature scheme which based on elliptic curve. The scheme, whose security is based on the elliptic curve separate logarithm difficult problem, has the very strong security. And in the key length and efficiency of carried out,it has the remarkable superiority. At last,it is ap- plied to a protocol of electronic voting. The performance analysis to the scheme shows that it is theoretically secure and suitable in practical applications.
