摘　　要：设计了一种抗攻击秘密共享匿名通信系统。该系统采用了秘密共享的思想来提高通信算法的可靠性和安全性。匿名通信时,通信双方存在多条链路;即使少量链路存在攻击者,仍然可以继续传输;发现攻击者后,也可以对链路进行动态地调整。分析发现该算法在抵抗前趋攻击等针对匿名通信的攻击方面优于传统的匿名通信算法。实验数据也表明:该算法在效率上虽然略劣于传统的匿名通信算法,但却以较小的效率代价获取了更高的可靠性和安全性。An anti-attack anonymous communication system based on secret sharing is designed.It improves its reliability and security by secret sharing.When communicating,there are several links between sender and receiver,and if few links is controlled by attacker,the communication continues and other links can be selected to replace the controlled links.Although its efficiency is not more than the some efficient system,it is more secure and more reliable because it prevents some attack or decrease the effect of attack.
