一种适于匿名通信系统的主动探测机制

An Active Mechanism of Detection for the Anonymous Communication System

匿名通信系统需要系统成员共同参与信息转发,恶意成员和不可靠成员将导致系统的匿名性能下降。在比特承诺方案的基础上,提出了一种适于匿名通信系统的主动探测机制,理论分析表明该机制能有效地匿名探测成员是否在线或假冒,同时通过认证机制确保数据在传输过程中免遭中间篡改攻击。

The performance of anonymous communication system relies on all members participating together in the system. But there are some malicious members and unreliable members in the anonymous systems which result to decrease the performance of anonymity. Based on the Bit commitment, an active mechanism of detection for the anonymous system is put forward in the paper. Theory analysis shows the mechanism is able to anonymously detect whether the member is online or counterfeit in the system. A! the same time, the mechanism protects the data from man-in-the-middle attack during the transmission course by the one-way hash function and authentication.
