Abstract
Embodiments of systems and methods to provide a firmware update to devices configured in a redundant configuration in an Information Handling System (IHS) are disclosed. In an illustrative, non-limiting embodiment, an IHS may include computer-executable instructions to receive a request for a secret known by the IHS, and attest the RAC by verifying that the public key exists in a manifest that is configured to store identifying information about a plurality of devices configured in the IHS. The request is signed using a private key of a first asymmetric key pair generated by a Remote Access Controller (RAC). Using a second public key of a second asymmetric key pair, the instructions encrypt the requested secret; and send the encrypted secret to the RAC, wherein the RAC is configured to use the second private key of the second asymmetric key pair to decrypt the encrypted secret.
