Abstract: The coverage of radar communication network gradually increases, the number of access users increases sharply, and the risk of terminal access expands. Radar communication terminal is one of the key equipment to block the access of bad users. Therefore, a security access control algorithm of radar communication terminal based on electronic signature technology is proposed. The security access control framework of radar communication terminal is build, applying CA authentication technology to authenticate the identity information of the user to enter the radar communication terminal, the user authentication information in the radar communication is stored terminal database, the user's personal electronic signature is made through electronic signature technology, and the electronic signature is matched through SIFT matching algorithm, It determines whether the electronic signature authentication information of the user of the radar communication terminal to be accessed is safe, to realize the control of the security access of the radar communication terminal. The experimental data shows that the security rate and security access efficiency of radar communication terminal obtained by the proposed algorithm are larger, and the security access control effect of radar communication terminal is better.
