摘　　要：密钥交换协议能够在两个人或多个人之间通过一个协议取得密钥并用于进一步的数据加密.基于群论中换位子的思想设计密钥交换协议,探讨置换群和矩阵群中由换位子实现的密钥交换及其应用.Key exchange protocol enables two or more parties get a key through a protocol that can be used in further data encryption.In the real world of cryptogram the key exchange plays a very important role.Based on the though of commutator,this paper designed a key exchange protocol.The key exchange protocol and it’s application were given,which based on the commutator of permutation group and matrix group.
