A secure affiliation between devices is provided to authenticate through different channel established by signal generators and sensors. Devices(102, 104) comprise radios(106, 108) for the major communication. A radio communication channel(110) is bidirectional. A signal generator(120) produces signals which detected by a sensor(122). An OOB communication channel(124) is one-way channel. Affiliate logic devices(130, 132) starts exchange of information through the radio communication channel. |
