Abstract
In the security access of distributed terminals in power communication networks,the trust degree of terminal nodes is not constant,which creates certain difficulties in the encryption process of data and leads to insufficient authentication accuracy of security access results.Therefore,a security access method for distributed terminals in power communication networks based on the hash-based message authentication code(HMAC)algorithm is proposed.The trust degree of terminal nodes is quantified by combining three indicators:intimacy degree,selfishness degree and honesty degree,and its instantaneous trust degree parameters is solved by adding attenuation factors and introducing the dynamic characteristics of node trust degree.The HMAC algorithm is used to add corresponding trust degree keys to terminal data for identity authentication.The authentication accuracy of the proposed method and the security degree of the access result are tested by decrypting in the terminal to achieve secure access.The experimental results show that the AUC value of the proposed method is 0.92,with high authentication ac-curacy and access results security degree,and it has a good application prospect.关键词
