Research on Data Encryption Technology in Computer Network Communication
Based on the security protection management requirements of network intrusion at-tacks and anonymous user access,using the Hadoop distributed software framework and the CP-ABE(Ciphertext Policy ABE)attribute based encryption algorithm,a cloud service control plat-form for access identity authentication and key sharing is constructed.The attribute authoriza-tion center independently generates the public key and master private key for network commu-nication,The data owner encrypts the set of data attributes based on the bilinear mapping rule of the CP-ABE encryption algorithm,while the data receiver decrypts the set of data attributes based on the ciphertext and decryption key of the access structure.The encrypted data is stored and shared at a fine-grained level on the public cloud service platform,effectively improving the security of data access and transmission management in computer network communication.
