Abstract
An escrowed key distribution system for over-the-air service provisioning of cellular telephones and other wireless communication devices provides a secure and efficient authentication key distribution method for wireless communications networks. To ensure security, an authentication key used to activate the wireless device is never transmitted over the air. In addition, mutual authentication is performed between the wireless communication device and the service provider using an embedded private-key algorithm to ensure proper authentication key transfer.
