Network user identification verification method, server and client terminal

Abstract

The invention discloses a network user identity authentication method, a server and a client, which solve the problem that user ID and password inputted by a user can be possibly intercepted and used illegally in network transmission process in the prior art. The identity authentication method includes that an identity authentication server receives a user ID sent from a client, and searches the password corresponding to the sent user ID in the corresponding relation of user ID and password; then the identity authentication server sends a random character string to the identity authentication client and encrypts the random character string to acquire a first encrypted cryptograph based on the searched password; the identity authentication server receives a second encrypted cryptograph sent from the identity authentication client; the identity authentication client encrypts a random character string based on the password inputted by user, so as to acquire the second encrypted cryptograph; the consistency of the first encrypted cryptograph and the second encrypted cryptograph is judged to determine the identity authentication result of the network user.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a network user identity verification method, server and client. Background technique [0002] With the rapid development of Internet technology, abundant network resources have brought great convenience to people's daily life. For example, people can communicate through instant messaging systems, and share video files through online video-on-demand. In order to ensure the security of network resources and to share network resources within the scope of authorized users, authentication is usually performed on users when they access network application systems. [0003] Please refer to the attached figure 1 , the basic principle of the existing network user authentication technology is: the user logs into the network application server, such as instant messaging (IM, Instant Messaging) system, file transfer protocol (FTP, File Transfer Protocol) server or electron...
