| 摘 要： | 提出了改进的Thompson群上的密钥交换协议,对字的生成过程进行控制,并设计实验证明了其拥有更强的安全性,可以抵御基于长度的攻击算法.由于基于长度的攻击在其他非交换群上的应用类似,该改进方法对其他非交换群上的密钥交换协议也同样适用.

| Abstract: | This paper proposed the key exchange protocol based on Thompson’s group, which controls the process of generating words, and designed experiments to show that the protocol can resist the length based attack. Moreover, because the length based attacks on other non commutative groups are similar to the one on Thompson’s group, it suggests that the approaches can be applied to any other non commutative group to resist the length based attack on that group. |
