摘要
为解决网络通信的匿名性问题,张胜等人提出一种基于身份一次性公钥方案,但该方案无法保证接收方的匿名性,并且其签名过程可以任意伪造,安全性无法保证。该文基于签密思想,构造了一个新的一次性公钥方案,该方案具有较高的效率,可以使得通信双方的匿名性同时得到满足。
In order to resolve network communication anonymity problem, Zhangsheng et al. presented a one-off public key scheme using identity-based cryptography but the scheme can not ensure the anonymity of the receiver and the signature process can be counterfeited, its security cannot be ensured. This paper constructs a new one-off public key scheme based on the conception of signcryption, the scheme is effective and satisfies synchronously the anonymity of the two parties in the communication.
