%X The Mix mechanism has provided a feasible solution to the realization of anonymous communication.But to a certain degree,the attackers can still obtain the correspondence relations through traffic analysis.In order to further improve the ability of Mix mechanism to resist the traffic analysis of message volume,a kind of scheme named group padding was proposed,and based on which,a new anonymous correspondence mechanism was designed.Algorithm analysis and the simulation results show that,compared with the traditional Mix mechanism,the newly proposed Mix mechanism based on group padding scheme can resist traffic analysis of message volume effectively,and needs lower extra bandwidth at the same time.
