匿名技术的抗攻击性研究

Anonymous communications for attack-resistant

研究了匿名技术的抗攻击性问题,定义了基于重路由的匿名通信系统模型,对匿名技术可能受到的攻击进行了分类和定义,分为消息码攻击、消息长度攻击、重放攻击、合伙攻击、泛洪攻击、消息量攻击、时间攻击、侧面攻击等8种,并对现有的主要匿名技术在抵抗攻击性方面进行了研究,为匿名技术的研究和设计新的匿名系统提供了依据.

An anonymity concept is introduced, and an anonymous communication system is defined on the basis of host-based rerouting mechanism and the attacks which anonymous communications suffer possibly, such as message coding attack, message length attack, replay attack, collusion attack, flooding attack, message volume attack, timing attack and profiling attack. Lastly, the attack(-resistant) main anonymity technologies are compared in order to give a basic idea to select and design an anonymous communication.
