摘要/Abstract

摘要： 提出了TETRA(terrestrial trunked radio)系统的新的鉴权协议，协议将鉴权算法的运行实体设为HLR(home location register)，而不是VLR(visitor location register)，当无法保证VLR和HLR之间的通信安全时，所提出的协议仍然可以有效避免产生对已知明文攻击的开放性，同时有利于满足将来网间漫游和认证算法自主性的需要，对于提高实际数字集群通信系统的安全性具有十分重要的意义。

Abstract: An authentication protocol for TETRA with authentication algorithm running in HLR instead of VLR is presented in this paper. The proposed protocol can effectively avoid the generation of an open attack for known text once the communication security between VLR and HLR can not be guaranteed.It is good for roaming between networks, meets the requirements for the independence of the authentication algorithm. The proposed protocol can improve the security of actual digital trunked system.

Key words: authentication, digital trunked system, challengeresponse protocol
