An integrated fault tolerant approach for data encryption and digitalsignature based on elliptic curve cryptography is proposed. Phis approach allows the receiver toverify the sender's identity and can simultaneously deal with error detection and data correction.Up to three errors in our approach can be detected and corrected. This approach has at least thesame security as that based on RSA system, but smaller keys to achieve the same level of security.Our approach is more efficient than the known ones and more suited for limited environments likepersonal digital assistants (PDAs), mobile phones and smart cards without RSA co-processors. 展开更多

针对ECDSA多出存在耗时的求逆运算,重新构造签名和验证方程,提出了一个无需求逆的数字签名方案,并对该方案的正确性、安全性和性能进行了分析。分析表明,新方案是正确、安全的,而且具有运算量较小、运算速度较快的特点。
