Rapid authentication method for wireless Mesh network backbone node switching

Abstract

The invention discloses a rapid authentication method for wireless Mesh network backbone node switching, which mainly solves the problem existing in the security of the rapid switching of a wireless Mesh backbone node which is not covered by the existing standard IEEE 802.11s, IEEE 802.11r and a series of China wireless local area network security standards. The authentication scheme is that when the backbone node is switched, a switching authentication request is transmitted to a switching target; a backbone node used as the switching target requests an authentication server for a switching authentication key; the authentication server generates a random key which is used as the switching authentication key and safely issues the switching authentication key to the backbone nodes involving in switching through a switching authentication key response message; and the two backbone nodes use the switching authentication key for rapid authentication in the switching process and adopt an elliptic curve key exchange algorithm to negotiate a session key. The invention has the advantages that the number of the transmitted messages is small, the forward secrecy is kept, the method can resist partial service denial attacks, and the method can be used for rapid network deployment for field operation, emergency command and emergency rescue and disaster relief.

Description

technical field [0001] The invention belongs to the technical field of wireless networks, and in particular relates to a secure communication method in a wireless Mesh network, which can be used for rapid network deployment in field operations, emergency command and emergency rescue. Background technique [0002] Wireless Mesh network is a technical extension of wireless local area network. It has the characteristics of flexible networking, automatic configuration, and strong mobility, and has broad application prospects. Mesh nodes (Mesh Points, MPs) in a wireless mesh network are meshed and interconnected in a wireless manner to form a backbone network for providing reliable network connections to terminals. figure 1 It is a schematic diagram of the existing wireless Mesh network topology. It consists of a backbone node MP to form a wireless backbone network. Customer nodes MC can access the wired network through the backbone network through one or more hops; the security-...
