Kind Code:
A
Abstract:
To provide a method, a device and a communication system for information exchange in a network spread environment.
An authenticated and secret session is attained. Thus, a 1st device 1 and at least a 2nd remote device 2 are used. A uni-directional radio communication channel 3 is started between the 1st device 1 and the 2nd remote device 2, a sequence is transmitted from the 1st device 1 to the 2nd remote device 2 via the uni-directional radio communication channel 3 to provide encrypted information to the 2nd remote device 2. An encrypted reply is transmitted to the 1st device 1 via a radio multiple address medium 4, by using the encrypted information for encryption.
