    Abstract: Embodiments of an invention for hardening data transmissions against power side channel attacks are disclosed. In one embodiment, a system includes a first agent and a second agent. The first agent is to transmit an encoded datum through an interface in a plurality of encoded packets. The second agent is to receive each of the plurality of encoded packets from the interface and decode each of the encoded packets to generate a plurality of decoded packets. Each of the encoded packets has the same Hamming weight. The Hamming distance between any two consecutively transmitted encoded packets is constant.

    Abstract: Method, apparatus, and system for qualifying CPU transactions with security attributes. Immutable security attributes are generated for transactions initiator by a CPU or processor core that identifying the execution mode of the CPU/core being trusted or untrusted. The transactions may be targeted to an Input/Output (I/O) device or system memory via which a protected asset may be accessed. Policy enforcement logic blocks are implemented at various points in the apparatus or system that allow or deny transactions access to protected assets based on the immutable security attributes generated for the transactions. In one aspect, a multiple-level security scheme is implemented under which a mode register is updated via a first transaction to indicate the CPU/core is operating in a trusted execution mode, and security attributes are generated for a second transaction using execution mode indicia in the mode register to verify the transaction is from a trusted initiator.

    Abstract: Apparatuses, methods, and systems for reconfiguring a secure system are disclosed. In one embodiment, an apparatus includes a configuration storage location, a lock, and lock override logic. The configuration storage location is to store information to configure the apparatus. The lock is to prevent writes to the configuration storage location. The lock override logic is to allow instructions executed from sub- operating mode code to override the lock.

    Abstract: A method and system for enforcing access control to system resources and assets. Security attributes associated with devices that initiate transactions in the system are automatically generated and forwarded with transaction messages. The security attributes convey access privileges assigned to each initiator. One or more security enforcement mechanisms are implemented in the system to evaluate the security attributes against access policy requirements to access various system assets and resources, such as memory, registers, address ranges, etc. If the privileges identified by the security attributes indicate the access request is permitted, the transaction is allowed to proceed. The security attributes of the initiator scheme provides a modular, consistent secure access enforcement scheme across system designs.
