Use information encryption technology for secure network transmission.

Abstract

Data encryption technology can not only encrypt and decrypt data, but can also implement digital signature, authentication and authentication and other functions, thus ensuring the confidentiality, integrity and authentication of data transmission over the network. In order to increase data security in network communication, the paper considers a hybrid encryption system that uses a triple DES algorithm with high security for encryption and decryption, and the two keys are encrypted using the RSA algorithm, thus ensuring the security of the DES triple key and solving the key management problem.
