Chaum [1,2]提出了一种简单有效的协议,旨在在对手监视所有通信链路的情况下提供匿名性。Chaum的协议被认为是不安全的。我们表明,Chaum的协议变得安全时,攻击模型是放松的,对手可以控制最多99%的通信链路。
Chaum [1, 2] suggested a simple and efficient protocol aimed at providing anonymity in the presence of an adversary watching all communication links. Chaum’s protocol is known to be insecure. We show that Chaum’s protocol becomes secure when the attack model is relaxed and the adversary can control at most 99% of communication links.
