Method and apparatus for securing communication of instructions to manage antenna power output
First Claim
1. An information handling system comprising:
- a standard absorption rate control register for storage of one or more code instructions executed to alter a power level of a transmission by an operably connected transmitting antenna;
a processor operably connected to the memory executing code instructions of an antenna power management security system to;
store a randomly generated number in a challenge register;
determine a first response value based on the randomly generated number;
read a second response value determined by the processor executing basic input output system code instructions and stored in a response register;
compare the first response value to the second response value;
if the first response value matches the second response value, receive a power management command to alter power supplied to the transmitting antenna from the processor executing basic input output system code instructions via a secure interface; and
store the power management command within the standard absorption rate control register within a preset time period for later execution by the processor.

Abstract
A system of antenna power management security may comprise a memory for storage in a standard absorption rate control register of code instructions executed to alter a transmitting antenna power level, and a processor operably connected to the memory executing code instructions of an antenna power management security system to store a randomly generated challenge number in a challenge register of the memory, determine a first response value based on the randomly generated challenge number, read a second response value determined by the processor executing code instructions of a basic input output system and stored in the memory, and if the first response value matches the second response value, allow the processor executing code instructions of the basic input output system to store a single command in the standard absorption rate control register within a preset time period, for later execution by the processor.
