Abstract
In a mobile satellite system, a mobile communication system includes a fraud detection and user validation system and method for commissioning the mobile communication system in the mobile satellite system. The method includes the steps of generating a first input signal by the mobile communication system upon initialization, and transmitting the first input signal from the mobile communication system to the central controller. The method also includes the steps of generating a first security key in the central controller using the first input signal, and generating a second security key in the mobile communication system using the first input signal and transmitting the second security key to the central controller. The central controller verifies the mobile communication system that transmitted the first input signal to commission it in the mobile satellite system. The verification process is responsive to a comparison of the first security key with the second security key. When the mobile communication system has been verified, information is transmitted throughout the mobile satellite system to enable future access and use of the mobile satellite system by the mobile communication system.
