AUTHENTICATION OF DEVICES IN A WIRELESS NETWORK

摘要

Various aspects are discussed, for example, a method is decsribed for authentication of devices in a wireless network involving NFC (Near Field Communication), wherein a device periodically switches its mode from a read mode, in which it is able to receive authentication data from one or more other devices, to a write mode, in which it sends out authentication data to the one or more other devices, according to a random time slot scheme. The device authenticates itself after having received authentication data from another device during the read mode, and the device switches permanently its mode to the write mode after being authenticated.

主权项

1. An apparatus comprising:
a chip configured and arranged to communicate using near field communication (NFC) and implement a bi-directional authentication process that includes
a read mode in which the chip operates to
receive an authentication identification;compare the received authentication identification to stored authentication identification on the chip; andauthenticate the apparatus based upon the comparison of the received authentication identification to the stored authentication identification; anda write mode in which the chip operates to
access the stored authentication identification; andtransmit the authentication identification to a second chip operating in the read mode, wherein the chip is further configured and arranged to enter the read mode after being powered on, to remain in read mode, and attempt the bi-directional authentication process until the apparatus is authenticated or until a time out occurs.
