Abstract:

Focused on the vulnerability to attack from external and internal nodes and hard management due to openness and jump more communication in wireless mesh network, a security network system has been brought forward based on research of the characteristic, the architecture and potential safety of mesh network, which contain four functions: access control, centralized management, avoid conflict and isolation fault. The system can ensure the safety of network by using some technologies such as firewall, identity authentication, cryptogram and intrusion detection. Which can authenticate the power of users and monitor the running status of mesh network by introduced the access controller in mesh backbone nodes. Also can identify the permissions of users, define access strategy and the level of security management by introduced the center manager in mesh gateway nodes. Analysis shows that the system enhances and improves the security of wireless mesh network, and has certain reference value for mesh network to practical application.

Key words: WMN, potential safety, access control, node, certification
