Secure encryption method for communication sensitive information based on multi-source information fusion

Traditional communication information encryption methods have problems such as low encryption efficiency and poor integrity of information encryption. Therefore, this paper proposes a secure communication sensitive information encryption method based on multi-source information fusion. Firstly, the structure level of multi-source information fusion is analyzed, and the sensitive communication information is collected by data collector and encrypted for secondary processing. Secondly, information fusion between multiple communication sensitive information is realized through Dempster combination rules. Finally, the similarity matrix is constructed, the support degree is calculated by information entropy, the output characteristic quantity of communication sensitive information encryption is obtained by key check, and the secure encryption function of communication sensitive information is obtained by circular shift method to achieve secure encryption of communication sensitive information. Experimental results show that when the amount of communication sensitive information data is 200GB, the encryption time of the proposed method is 0. 98s, and the noise intensity is 90dB, the encryption integrity of the proposed method is 96%. The results show that the proposed method has high security and efficiency in communication sensitive information encryption.
