  • This abstract for appeared for patent application number 17714324 Titled 'SECURE WIPE OF DATA PROCESSING UNIT USING FIRMWARE CAPSULE'

Simplified Explanation

This abstract describes an information handling system that includes a processor, a data processing unit, and a management controller. The management controller is responsible for managing the system outside of the main processor. It can obtain information about the hardware and capabilities of the data processing unit. Based on this information, it can generate a firmware capsule that will be executed during the basic input/output system phase of the data processing unit. The purpose of this firmware capsule is to securely erase the contents of the memory in the data processing unit. The management controller then communicates this firmware capsule to the data processing unit during the operating system phase and causes the unit to reboot to its basic input/output system phase. This allows the drivers in the firmware capsule to be executed and securely erase the memory.


Original Abstract Submitted

An information handling system may include a processor, a data processing unit communicatively coupled to the processor, and a management controller communicatively coupled to the processor and the data processing unit and configured for out-of-band management of the information handling system. The management controller may further be configured to obtain a hardware inventory and capabilities of the data processing unit; based on the hardware inventory and capabilities, generate a firmware capsule for execution during a basic input/output system phase of the data processing unit to cause a secure erasure of contents of a memory of the data processing unit; and communicate the firmware capsule to the data processing unit during an operating system phase of the data processing unit and cause the data processing unit to reboot to its basic input/output system phase in order to execute drivers of the firmware capsule in order to securely erase the memory.
