Abstract: Embodiments of electronic circuits, computer systems, and associated methods include a module that accesses memory using virtual addressing, the memory including local memory that is local to the module and nonlocal memory that is accessible via a system bus coupled to the module, the module including logic coupled to the local memory via a local bus. The logic is configured to receive a memory access specified to a virtual address, determine whether the virtual address is within the local memory, and direct the memory access either to the local memory via the local bus or to the nonlocal memory via the system bus based on the determination.

Abstract: Embodiments of electronic circuits enable security of sensitive data in a design and manufacturing process that includes multiple parties. An embodiment of an electronic circuit can include a private key embedded within the electronic circuit that is derived from a plurality of components including at least one component known only to the electronic circuit and at least one immutable value cryptographically bound into messages and residing on the electronic circuit, public key generation logic that generates a public key to match the private key, and message signing logic that signs messages with the private key.
