Problems solved by technology

Its limitations are: (1) the complexity is too high, and it is not easy to realize; (2) the way of entering passwords is used to connect online. Although the passwords are hashed to improve security, the threat of password guessing attacks has not been eradicated, especially When the password selected by the user is not strong enough, the password guessing attack is more likely to be successful; (3) The use of time stamp in the SPX model is similar to the Kerberos system, and the system clock must be kept synchronized, so the ability to prevent replay attacks is poor
Because a large number of user names and passwords are not easy for users to remember, users often use simple information as passwords or set the same password, which brings huge hidden dangers to security. For this reason, managers need to create multiple user databases. Naturally cause inconvenience and cumbersome management

Embodiment Construction

[0050] The present invention will be described in further detail below with reference to the accompanying drawings.

[0051] refer to figure 1 , The cross-security domain network authentication and key distribution system of the present invention includes: a verification server, a client access subsystem, and an application service subsystem. Among them, the client access subsystem is composed of users and proxy servers; the application service subsystem is composed of several application servers. The working process of the system is:

[0052] First, in the client access subsystem, the user accesses the authentication server through a proxy server, and forwards the user's public key certificate and user identity information with digital signature to the authentication server. The proxy server only plays a role in the authentication process. "Transparent transmission" function, the user authentication work is completed by the authentication server.

[0053] Secondly, after r...

Abstract

The invention relates to a network authentication and key distribution method. based on the single point log-in, connecting one authentication server and several application servers into each safety field; distributing the authentication and keys according to the demand of application server when the user accesses into different safety fields. First, user processes the identification authentication in said safety field to attain a server card communicating with the application server in another safety field; then the user at the accessed safety field validates the card to attain the service connecting with the application server; at last, the user processes the identification authentication on said application server. The inventive system comprises a client access subsystem, an application service subsystem and a validate server which can complete the user identification authentication and the service authorization. The invention has simple process, with high safety and effect.

Description

technical field [0001] The invention belongs to the technical field of communication network security, in particular to a token-based single sign-on method applicable to various distributed network environments across security domains, which provides users with access to distributed networks that only need to perform One-time identity authentication can realize the authentication and key distribution services across security domains for accessing multiple systems, ensuring the security and effectiveness of distributed collaborative work. Background technique [0002] With the popularization and application of distributed networks, network access security issues are getting more and more attention. Authentication is a key technology of network access security, and it plays an extremely important role in preventing malicious attacks and protecting the rights and interests of legitimate users. Authentication includes two meanings: one is identity authentication, that is, to co...
