Abstract:
Various embodiments are described herein for a mobile communication device that authenticates a smart battery prior to use. The mobile device includes a main processor and a device memory. The device memory stores first and second portions of security information used for authentication. The smart battery includes a battery processor and a battery memory. The battery memory stores a third portion of security information used for authentication. The main processor sends an authentication request including the first portion of security information to the battery processor, and the battery processor generates a response based on the first and third portions of security information and sends the generated response to the main processor. The smart battery is authenticated if the generated response matches the second portion of security information.
