Abstract:

A general model of central resource distribution is proposed by studying the designs of blockingresistant anonymity system and considering the problem of access point information distribution. Based on this model, analysis of its specialized model with randomchoice strategy is given, which could be used for evaluating the antiattack ability of such systems and how much it costs to counter for the attacker. Simulation shows that the practical blockingresistant systems could select the appropriate amount of access points for each user and have a large number of active access points to improve the ability, and the censor could make appropriate investment according to the amount of access points to counter.

Key words: anonymous communication, blocking resistance, censorship resistant, resource distribution
