Abstract
A method of certifying a state of a platform includes receiving one or more software elements of a software stack of the platform by an authentication module and performing a hash algorithm on the software stack to generate one or more hash values. The software stack uniquely determines a software state of the platform. The method includes generating creation data, a creation hash, and a creation ticket, corresponding to the hash values and sending the creation ticket to the platform. The method also includes receiving the creation ticket by the authentication module and certifying the creation data and the creation hash based on the creation ticket. The method further includes generating a certified structure based on the creation data and performing the hash algorithm on the certified structure to generate a hash of the certified structure. The certified structure uniquely determines the software state of the platform.
