| 摘 要： | 数字签名技术不仅能够提供加密和解密，而且能够确认参与者的身份，防止恶意的伪造、篡改，在网络通信安全方面起到重要的保护作用。椭圆曲线密码系统与其他公钥密码系统相比，除具有安全性高外，还有计算负载小，密钥尺寸短，占用带宽少等优点。新的基于椭圆曲线的具有消息恢复功能的数字签名方案，给出了验证协议和否认协议，并对方案的安全性进行了讨论，解决了普通ECC数字签名方案不能实现消息恢复的问题。

| Abstract: | Digital signature technology can not only provide encrypt and decrypt but determine the identity of participants,prevent malicious forgery and distortion and play am important role in the safety of network service.Compared with other public-key cryptosystem,the elliptic curve cryptosystem has the advantages of higher safety,less computing load,shorter encryption key and occupying less bandwidth.The new signature scheme with message recovery based on the elliptic curve gives the way to test and defy agreements,discusses the safety of the scheme and solves the problem of the message recovery which can not be realized by the general ECC signature scheme. |
