System and method for signing and interlocking a boot information file to a host computing system

A manageability controller of a host computing system, comprising:

• a machine readable medium that stores program instructions;
• and
• a processing resource operably coupled to the machine readable medium, wherein the processing resource executes the program instructions to:
• receive a boot information file of the host computing system from a processor of a computing device;
• sign the boot information file with a hashed data of a unique identifier, to generate a signed boot information file;
• communicate the signed boot information file to the processor;
• in response to successful download of the signed boot information file by the processor, update a boot database stored in a non-volatile random-access memory of a firmware engine of the host computing system with a thumbprint data of the signed boot information file for interlocking the host computing system to the signed boot information file;
• and
• append the boot information file stored in a non-volatile storage drive of the host computing system, by using the hashed data of the unique identifier to generate an appended boot information file, wherein the appended boot information file and the signed boot information file are similar files.

A non-transitory machine readable medium that stores instructions executable by a manageability controller of a host computing system, wherein instructions comprising:

• a first instruction to receive a boot information file of the host computing system from a processor of a computing device, wherein the processor is separate from the manageability controller;
• a second instruction to sign the boot information file with a hashed data of a unique identifier, to generate a signed boot information file;
• a third instruction to communicate the signed boot information file to the processor;
• a fourth instruction to update a boot database stored in a non-volatile random-access memory of a firmware engine of the host computing system with a thumbprint data of the signed boot information file for interlocking the host computing system to the signed boot information file, in response to successful download of the signed boot information file by the processor;
• and
• a fifth instruction to append the boot information file stored in a non-volatile storage drive of the host computing system, by using the hashed data of the unique identifier to generate an appended boot information file, wherein the appended boot information file and the signed boot information file are similar files.
