Abstract

The invention provides an encrypting method for network data transmission. The method comprises the following steps of when the data are sent, enabling a sending party to perform hardware encryption on the data in a local hardware encryption and decryption device according to a public key (Kp) of a receiving party, and send the data to the receiving party; when the data are received, enabling the receiving party to perform hardware decryption on the received data in the local hardware encryption and decryption device according to a self private key (Kp); generating the public key (Kp) and the private key (Ks) of the sending party or the receiving party in the local hardware encryption and decryption device. By adopting the technical scheme, the method has the advantages that the data are directly encrypted and decrypted in the data encryption and decryption device, the internal information of the data encryption and decryption device is protected by the identify identification method, the consumption of CPU (central processing unit) resource of the data sending and receiving equipment is avoided, and the confidential effect of the data is better by performing the data encryption on the data; meanwhile, by using an asymmetric encryption algorithm and a symmetric encryption algorithm, the private key is completely hidden in the data encryption and decryption device in a ciphertext way, and the better encryption effect is obtained.

Description

technical field [0001] The invention relates to the fields of data transmission and data security, in particular to a security method for network data transmission. Background technique [0002] In recent years, with the development of computer network technology, the use of network for data transmission has also entered people's daily life and work, and data information leakage has become the most concerned issue. Many threats may lead to data loss or leakage, and further cause users' trust in instant messaging services, so there is a great demand for products that ensure data security. [0003] In order to improve the security of data information, the current effective method is to encrypt data, so that data can only be browsed by designated people through encryption to ensure data security. Currently, there are three common data encryption methods: [0004] The first method: use symmetric encryption algorithm to encrypt data. Symmetric encryption algorithm is an earlier...
