摘要
椭圆曲线公钥密码体制以其特有的优越性被广泛应用于电子商务等领域。分析了椭圆曲线数字签名算法的优缺点,在构造签名方程的基础上,提出了一种新的无求逆的签名算法,通过理论证明和编程实验,验证了算法的有效性,简化了运算的复杂程度,同时保证了算法的安全性。
The elliptic curve cryptosystem has been applied to many fields such as E-business. The advantage and disadvantage of elliptic curve digital signature algorithm are analysed. Based on the constructing of signature equation, a new signing schedule of non-inversion is offered. By theory proof and programming practice, the signature schemes are developed with better performance. Also, the operations are simplified and the security of algorithm is improved.
