Embodiment Construction

[0042] Below in conjunction with accompanying drawing, the present invention will be further described:

[0043] Applicable environment of the present invention: an overall network is divided into several network areas, and each network area is called a domain; each domain has many nodes and a cluster head node, and nodes in a domain authenticate to the cluster head node, and the cluster head node Then exchange data with the outside world; when the network is established, the node ID will be registered with the cluster head as a registered node, and the cluster head will store all registered nodes in the legal node table. In addition to the legal node table, the cluster head also has a command node table and an authenticated node table.

[0044] Attached below figure 1 Concrete steps of the present invention are further described as follows:

[0045] Step 1, the cluster head and nodes are started, and the legal node table, command node table and authenticated node table are ...

Abstract

The invention discloses a node authentication method for avoiding authentication congestion. The authentication method comprises the following steps of: 1, passive authentication; 2, active authentication; 3, fast re-authentication; and 4, fast cross-domain authentication. According to the authentication method, the passive authentication is carried out during initialization, and authentication of other three steps is allowed after the initialization; the active authentication is spontaneous authentication of nodes; the fast re-authentication is used for fast recovering authentication connection of an authentication center after a cluster head is crashed; and the fast cross-domain authentication eliminates inconvenience of node migration domain transfer. By the method, the authentication congestion of the nodes in a network environment is effectively avoided, the problems of slow recovery of the crashed cluster head and incompatible authentication of the nodes are solved, and normal work of an authentication system is ensured.

Description

technical field [0001] The invention belongs to the field of computer technology, and further relates to a node authentication method for avoiding authentication blocking in the field of network technology. The invention can realize node authentication in order and ensure safe operation of the system in the authentication between the user and the host and between the host and the host, thereby avoiding the problem of easily causing authentication block in the network environment. Background technique [0002] Identity authentication is the process of confirming the identity of the operator in the information system. Identity authentication can be divided into the authentication between the user and the host and the authentication between the host and the host. With the improvement of people's security awareness and the enhancement of information system security requirements, as the first line of protection for information systems, identity authentication technology has been ...
