Abstract：The security problem of fast handoffs in WLAN mesh networks with mobile mesh access point （MAP） was analyzed. Based on the neighbor graph fast handover method and matrix-based key pre-distribution scheme, an authentication scheme for fast handoff was proposed. The scheme is suitable to the WLAN mesh networks with mobile MAP. Based on Canetti - Krawczyk model, the improved d - way handshake protocol in the scheme was analyzed. And computation overhead and memory cost were evaluated. The results show that it is SK - secure in UM if the pseudorandom function and MAC function in use are secure against chosen message attacks. The performance shows that the proposed scheme has less computation overhead and memory cost.
