AUTHENTICATION OF DEVICES IN A WIRELESS NETWORK
First Claim
1. A method for authentication of devices in a wireless network, whereina device is operated in an authentication mode in which it periodically switches 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, and vice versa according to a random time slot scheme,the device authenticates itself after having received authentication data from another device during the read mode, andthe device switches permanently its mode to the write mode after being authenticated.

Abstract
A method for authentication of devices (D1, D2, D3) in a wireless network, wherein—a device (D1, D2, D3) periodically switches its mode from a read mode, in which it is able to receive authentication data from one or more other devices (D1, D2, D3), to a write mode, in which it sends out authentication data to the one or more other devices (D1, D2, D3), according to a random time slot scheme,—the device (D1, D2, D3) authenticates itself after having received authentication data from another device (D1, D2, D3) during the read mode, and—the device (D1, D2, D3) switches permanently its mode to the write mode after being authenticated.

a device is operated in an authentication mode in which it periodically switches 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, and vice versa 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.
- 7. A wireless network device which comprises an authentication protocol which is provided to operate the device in an authentication mode in which it periodically switches 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, and vice versa according to a random time slot scheme, wherein the device is adapted to authenticate after having received authentication data from another device during the read mode, and wherein the device is further adapted to switch permanently its mode to the write mode after being authenticated.

12. A system for authentication of devices in a wireless network, comprising
at least two devices each having an authentication mode in which a device periodically switches its mode from a read mode, in which it receives 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, wherein in the system one of the at least two devices 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.
