Safe network information transmission method

Abstract

The invention discloses a safe network information transmission method. The method includes that a client sends a service request to a server; a server side verifies a user message in the service request and a client internet protocol (IP) address, and the server side establishes a session with the client if the verification passes; the server side generates a secret key, encrypts the secret key through a public key of the client and sends the secret key to the client; the client decrypts secret key information through a private key, encrypts decrypted secret key information through a public key of the server side and sends the secret key information to the server side; the server side performs digital signature to data of the service request, encrypts the data and digital signature information through the secret key and sends the data and the digital signature information to the client; and the client decrypts the data and performs consistent verification, the information which doesn't pass the consistent verification is discarded, the server side is applied for retransmission, and the information which passes the verification is stored into a local data base. By means of the safe network information transmission method, safety of information transmission is greatly improved.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a safe and efficient network information transmission method, which is mainly used in the fields of network data communication between a server and a client, information encryption, security identity authentication and the like. technical background [0002] With the rapid development of computer network technology, the network has become the world's largest public data source, and its scale is still growing rapidly. While the Internet has greatly changed people's lives and promoted social progress, because it is an open system for the public, with the continuous expansion of the scope of network applications, the leakage of confidential information has become increasingly serious, resulting in Network security issues are also becoming more and more prominent. Computer network information may be illegally embezzled, exposed or tampered with in the process of use and transmissi...
