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.
