Abstract
Methods and apparatus are disclosed to self authorize platform code. A disclosed example method includes storing a hash of a first public key in a policy data structure of a platform at a first time, extracting a second public key from a signature block associated with a data structure to be authenticated at a second time, when a hash of the second public key matches the hash of the first public key, extracting an encrypted hash from that signature block, decrypting the encrypted hash using the second public key to determine a decrypted value, and comparing the decrypted value with a hash of the data structure to verify the data structure integrity.
