Abstract:
A mechanism for providing secure feature and key management in integrated circuits is described. An example method includes receiving, by a root authority system, data identifying a command that affects operation of an integrated circuit, singing, by the root authority system, the command using a root authority key to create a root signed block (RSB), and providing the RSB to a security manager of the integrated circuit.

Claim (Index 2):
A method comprising:\n obtaining, by a delegate authority system, a base key; deriving, by the delegate authority system, a mixed key using the base key; deriving, by the delegate authority system, a transport key using the mixed key; obtaining, by the delegate authority system, a payload key; encrypting the payload key using the transport key to obtain an encrypted payload key; deriving, by the delegate authority system, a validator using the encrypted payload key and the mixed key, wherein the validator enables a security manager core of an integrated circuit to verify that the encrypted payload key is valid and unmodified; receiving, by the delegate authority system, delegate input parameters; signing, by the delegate authority system, the delegate input parameters, the encrypted payload key, and the validator using a delegate private key to create a delegate signed block (DSB), wherein the delegate private key is associated with the delegate authority system; and providing the DSB to the security manager core of the integrated circuit, wherein the security manager core to extract a payload specifying at least one of a restriction, a binding, or a value intended for a hardware feature of the integrated circuit, in response to a signature of the DSB being verified by the security manager core.
