Wireless Authentication and Transaction-Confirmation Token

Our new system combines Wi-Fi with user-authentication tokens to authenticate consumer financial transactions. To achieve this goal while maintaining maximum usability and compatibility, our token tunnels data through new side channels including the SSID field, packet timing, and packet length. These new point-to-point side-channels in Wi-Fi allow a token and PC to directly exchange messages - even while the PC is also connected to an access point. The result is a token that can authenticate transactions using only one touch by the user.
