WIRELESS DEVICE AUTHENTICATION AND SECURITY KEY MANAGEMENT
First Claim
1. A method for updating a cryptographic security key associated with a wireless device and an authentication module, the method comprising:
- receiving, from an information processing system, an over-the-air programming message having security key update information comprising a new security key associated with the wireless device and the authentication module;
processing the security key update information;
extracting, in response to the processing, the new security key from the security key update information; and
updating, in response to the extracting, an existing security key with the new security key that has been extracted.

Abstract
A method and wireless device for updating at least one cryptographic security key (116) associated with a wireless device (104) and an authentication module (108). An over-the-air programming message comprising security key update information is received (804) from an information processing system (118). The security key update information is processed (808). At least one new security key is extracted from the security key update information in response to the processing (806). At least one existing security key (116) is updated with the at least one new security key (124) that has been extracted.
