A SECURE MULTIPARTY MICROPAYMENT PROTOCOL FOR INTERNET ACCESS OVER WLAN WIRELESS MESH NETWORKS

We propose a secure multiparty micropayment (MMPay) protocol for internet access over WLAN mesh networks, that enables a secure network access anywhere and anytime according to user desire. The incontestable MMPay scheme has been devised from existing micropayment schemes emulating their good attributes and eliminating security vulnerabilities and difficulties, which includes: hash-chain based variable length payment instrument, user's payment certificate at smartcard, and an efficient redemption approach. The security analysis and simulation results shows that MMPay is secure and efficient, and thus will be a practical billing solution for future large-scale WLAN mesh networks.
