Abstract: The present invention is a method, apparatus, and system to generate a key hierarchy for use in an isolated execution environment of a protected platform. In order to bind secrets to particular code operating in isolated execution, a key hierarchy comprising a series of symmetric keys for a standard symmetric cipher is utilized. The protected platform includes a processor that is configured in one of a normal execution mode and an isolated execution mode. A key storage stores an initial key that is unique for the platform. A cipher key creator located in the protected platform creates the hierarchy of keys based upon the initial key. The cipher key creator creates a series of symmetric cipher keys to protect the secrets of loaded software code.

Abstract: A method of remote attestation for a special mode of operation comprises storing an audit log within protected memory of a platform. The audit log is a listing of data representing each of a plurality of Iso X software modules loaded into the platform. The audit log is retrieved from the protected memory in response to receiving a remote attestation request from a remotely located platform. Then, the retrieved audit log is digitally signed to produce a digital signature for transfer to the remotely located platform.

Abstract: A technique is provided to execute isolated instructions according to an embodiment of the present invention. An execution unit executes an isolated instruction in a processor operating in a platform. The processor is configured in one of a normal execution mode and an isolated execution mode. A parameter storage containing at least one parameter to support execution of the isolated instruction when the processor is configured in the isolated execution mode.

Abstract: An access transaction generated by a processor is configured using a configuration storage containing a configuration setting. The processor has a normal execution mode and an isolated execution mode. The access transaction has access information. Access to the configuration storage is controlled. An access grant signal is generated using the configuration setting and the access information. The access grant signal indicates if the access transaction is valid.

Abstract: A method is provided for loading a packed floating-point operand into a register file entry having one or more associated implicit bits. The packed floating point operand includes multiple component operands. Significand and exponent bits for each component operand are copied to corresponding fields of the register entry, and the exponent bits are tested to determine whether the component operand is normalized. An implicit bit corresponding to the component operand is set when the component operand is normalized.
