In order to improve the security of communication data in a computer network,a secure encryption method for communication data in a computer network based on a hybrid algorithm of AES and ECC is proposed.The frequency distribution of communication data at the edge of the computer network is obtained through time domain analysis,and the feature vectors of the communication data are extracted by discretising the noise within the communication data according to the density of redundant information in the communication data.According to the plaintext space encryption of the communication data,the ciphertext value of the communication data to be encrypted is calculated,and the encryption process of the communication data of the computer network is constrained into the computation of the encryption function,and the constraints of the secure encryption of the communication data are set.The plaintext of communication data is encrypted by AES algorithm,the AES key is encrypted by ECC algorithm,and the key ciphertext of communication data is generated by combining AES and ECC to achieve the secure encryption of communication data.The experimental results show that the method provided can ensure the security of communication data in the computer network,and can control the attacked index of the encrypted communication data within 0.1 to improve the encryption effect of the communication data.
