[Abstract]:With the increasing demand for wireless access and the development of technology, wireless MESH network (Wireless Mesh Networs, WMNs), as a key technology to solve the "last kilometer" problem of the Internet, has been widely applied and studied in industry and academic fields. Seamless and secure handover has always been an important topic in the research of wireless MESH networks. The design of secure handover authentication protocol to reduce the handover delay of mobile terminals, make users can still obtain a stable and secure wireless connection while switching, and protect the privacy of users, which has profound theoretical research and practical significance. In this paper, the handoff authentication schemes in wireless MESH networks are studied and designed from three angles: the handoff authentication protocol based on symmetric cryptography (Ticket), the handoff authentication protocol based on public key cryptography (proxy signature), and the authentication protocol based on public key cryptography (proxy signature). Handoff authentication protocol with privacy protection (using blind signature). 1. Handoff authentication protocol based on Ticket: in wireless MESH network, using symmetric key algorithm and without the participation of third party, a handover authentication protocol based on ticket is designed to ensure the integrity of data and the validity of participants. Effective reduction of computing and communication overhead during handover. 2. Handoff Authentication Protocol based on proxy signature: under the background of wireless MESH network, combined with the cooperation function of Mesh router, Using public key cryptography (proxy signature), a local handoff authentication protocol (Local Joint Fast Handoff),) is designed to ensure that the authentication server does not need to participate in the handover process and reduces the communication delay. Blind signature is used to implement privacy protection handoff authentication protocol: under the premise of low handover delay, blind signature and partial blind signature are used to enable wireless MESH network to provide identity anonymity and pseudonym based location anonymity services for users.
