The Security Encryption Method of Computer Network Communication Under Genetic Algorithm is Discussed

With the continuous development of computer network communication technology, the development speed of the Internet era has reached a new height, and in the context of more and more intelligent information management, information security issues have attracted more and more attention. How to achieve fast encryption processing has become one of the hot types of research, and the traditional communication encryption method cannot solve the problem of the lag of data information application when decrypting and reading encrypted information, and the decryption processing is unreasonable. Therefore, a genetic algorithm is proposed and combined with composite chaotic sequence to optimize information encryption processing. First, the information security theory is used to process computer network information, and the indicators are divided according to the requirements of information encryption processing to reduce the interference factors in information management. Then, the information security theory encrypts the computer network information, forms an information encryption processing scheme, and comprehensively analyzes the information management results. MATLAB simulation shows that under the condition of certain processing standards, the genetic algorithm is better than the traditional communication encryption method for computer network information encryption processing accuracy and information management time.
