摘　　要：单一通信协议无法满足在复杂环境下网络认证的需求。提出面向交直流混联电网的多协议安全认证集成技术。为满足用户的前向安全性判定,以通用多信任域协议建立会话双方的密钥协议,更新算法的同时更新密钥,使得在不同信任域中,会话内容不被泄露;利用钥匙分发中心管理机制和公开密钥加密协议,分别对会话双方展开数字签名的验证,通过双向身份验证即可同意会话请求。仿真实验结果表明:会话发起后在出现噪声干扰的多个时刻下,所提方法均停止通信,避免了信息丢失;当噪声干扰出现次数由0增加到350次时,所提方法的正确终止通信准确率始终保持在90%以上。As a single communication protocol cannot meet the requirements of network authentication in a complex environment, a multi-protocol security authentication integration technology for AC/DC hybrid network is proposed in this paper. To meet the user’s forward security judgment,the key protocol of both sides of the session is established with the general multi trust domain protocol,and the key is updated at the same time,so that the session content is not disclosed in different trust domains. With the key distribution center management mechanism and public key encryption protocol,the digital signatures of both sides of the session are verified respectively,and the session request can be agreed through twoway authentication. Simulation results show that the proposed method stops communication and avoids information loss at multiple times of noise interference after session initiation. When the number of noise interference increases from 0 to 350,the correct termination accuracy of the proposed method remains above 90%.
