US 2021/0240832 A1 · SYSTEMS AND METHODS FOR AUTOMATIC BOOT TO AUTHENTICATED EXTERNAL DEVICE

Abstract

An information handling system may include a processor, an external port communicatively coupled to the processor and configured to receive an external information handling resource and couple the external information handling resource to the processor, and a basic input/output system comprising a program of instructions executable by the processor. The program of instructions may be configured to cause the processor to: (i) determine if the external information handling resource coupled via the external port has a signed payload manifest stored thereon, the signed payload manifest comprising information regarding files of a bootable payload stored on the external information handling resource; (ii) if the external information handling resource has a signed payload manifest stored thereon, attempt to authenticate the signed payload manifest; (iii) if the signed payload manifest is authenticated, attempt to verify the files of the bootable payload based on the information with the signed payload manifest regarding files of the bootable payload; (iv) if the files of the bootable payload are verified, attempt to verify a bootable image of the bootable payload; and (v) if the bootable image is verified, cause the information handling system to boot from the bootable payload.

Dependent claims

An information handling system comprising:

a processor;
an external port communicatively coupled to the processor and configured to receive an external information handling resource and couple the external information handling resource to the processor;
and
a basic input/output system comprising a program of instructions executable by the processor and configured to cause the processor to:
determine if the external information handling resource coupled via the external port has a signed payload manifest stored thereon, the signed payload manifest comprising information regarding files of a bootable payload stored on the external information handling resource;
if the external information handling resource has a signed payload manifest stored thereon, attempt to authenticate the signed payload manifest;
if the signed payload manifest is authenticated, attempt to verify the files of the bootable payload based on the information with the signed payload manifest regarding files of the bootable payload;
if the files of the bootable payload are verified, attempt to verify a bootable image of the bootable payload;
and
if the bootable image is verified, cause the information handling system to boot from the bootable payload.

An article of manufacture comprising:

a computer readable medium;
and
computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
determine, with a basic input/output system of an information handling system, if an external information handling resource coupled to the information handling system via an external port of the information handling system has a signed payload manifest stored thereon, the signed payload manifest comprising information regarding files of a bootable payload stored on the external information handling resource;
if the external information handling resource has a signed payload manifest stored thereon, attempt, with the basic input/output system, to authenticate the signed payload manifest;
if the signed payload manifest is authenticated, attempt to verify, with the basic input/output system, the files of the bootable payload based on the information with the signed payload manifest regarding files of the bootable payload;
if the files of the bootable payload are verified, attempt to verify, with the basic input/output system, a bootable image of the bootable payload;
and
if the bootable image is verified, cause the information handling system to boot from the bootable payload.
