Research network security encryption problem.In order to protect the security of network communication and information,the communication message information encryption is necessary.But when communication network is attacked,partial communication message is intercepted and vice versa.Traditional AES encryption algorithm in which encryption and decryption used the same keys,can not effectively prevent the cyber attacks and interceptions of messages,leading to the problem that network communication safety is not high.This paper put forward an improved Rijndael method,by using random depth first searching algorithm,different paths were chosen to identify different encrypted data.Different keys were used for encryption and decryption to reduce the rate of crack message,avoiding the problem that encryption and decryption share the same key will result weak ability of anti-attack.Experiments show that the improved algorithm has stronger anti-interference ability and can strengthen the network security effectively.
