Abstract
In accordance with the present disclosure, a system and method for multilayered authentication of trusted platform updates is described. The method may include storing first cryptographic data in a personality module of an information handling system, with the first cryptographic data corresponding to a verified firmware component. A second cryptographic data may also be determined, with the second cryptographic data corresponding to an unverified firmware component. The unverified firmware component may be stored in a memory element of the information handling system, and the second cryptographic data may be determined using a processor of the information handling system. The method may further include determining if the first cryptographic data matches the second cryptographic data and updating firmware in the information handling system with the unverified firmware component if the first cryptographic data matches the second cryptographic data, and the unverified firmware component includes a digital signature of a manufacturer.
