摘要
现有的北斗终端接入认证协商协议存在着认证延时较长、精度较低的缺陷,为了解决上述问题,提出基于标识认证和SM2算法的北斗终端接入认证协商协议研究。依据北斗终端接入认证特点,搭建北斗终端接入认证协商协议框架,以此为基础,利用SHA-1算法注册北斗终端,得到终端接入标识以及公钥,采用SM2算法协商终端与北斗系统接入认证密钥,依据协商密钥,利用标识认证算法实现了终端与北斗系统的接入认证。通过测试结果显示:提出的北斗终端接入认证协商协议极大地降低了认证延时,提高了认证精度,充分说明提出的北斗终端接入认证协商协议具备更好的认证效果。
The existing Beidou terminal access authentication negotiation protocol has the defects of long authentication delay and low accuracy.In order to solve the above problems,a Beidou terminal access authentication negotiation protocol based on the identification authentication and the SM2 algorithm is proposed.According to the characteristics of the access authentication of the Beidou terminal,a Beidou terminal access authentication negotiation protocol framework is set up,the Beidou terminal is registered by using the SHA-1 algorithm,the terminal access identification and the public key are obtained,the SM2 algorithm negotiation terminal and the Beidou system are used for accessing the authentication key,and according to the negotiation key,The identification authentication algorithm is used to realize the access authentication between the terminal and the Beidou system.The results of the test show that The proposed Beidou terminal access authentication negotiation protocol greatly reduces the authentication delay and improves the authentication accuracy,which fully shows that the proposed Beidou terminal access authentication negotiation protocol has better authentication effect.
