Abstract: A mechanism for providing secure feature and key management in integrated circuits is described. An example integrated circuit includes a secure memory to store a secret key, and a security manager core, coupled to the secure memory, to receive a digitally signed command, verify a signature associated with the command using the secret key, and configure operation of the integrated circuit using the command.
