摘要： Embodiments include methods for securely provisioning copies of an electronic circuit. A first entity (e.g., a chip manufacturer) embeds one or more secret values into copies of the electronic circuit. A second entity (e.g., an OEM): 1) embeds a trust anchor in a first copy of the electronic circuit; 2) causes the electronic circuit to generate a message signing key pair using the trust anchor and the embedded secret value(s); 3) signs provisioning code using a code signing private key; and 4) sends a corresponding code signing public key, the trust anchor, and the signed provisioning code to a third entity (e.g., a product manufacturer). The third entity embeds the trust anchor in a second copy of the electronic circuit and causes the electronic circuit to: 1) generate the message signing private key; 2) verify the signature of the signed provisioning code using the code signing public key; and 3) launch the provisioning code on the electronic circuit. The electronic circuit can authenticate itself to the OEM using the message signing key pair.

摘要： Embodiments of methods of provisioning an electronic circuit enable security of sensitive data in a design and manufacturing process that includes multiple parties. In an illustrative embodiment, a method of provisioning an electronic circuit includes generating at least one secret value, embedding the at least one secret value into the electronic circuit, programming into the electronic circuit a private key derivation function that derives the private key from the at least one secret value and a trust anchor, and programming into the electronic circuit a public key generation function that generates a public key matching the private key. The method can further include receiving for execution trust anchor-authenticated logic that contacts a predetermined actor of the plurality of distinct actors and communicates to the predetermined actor a message signed with the private key.

摘要： Under the direction of a first party, an integrated circuit (IC) device is configured to temporarily enable access to a debug interface of the IC device via authentication of the first party by a challenge/response process using a key of the IC device and a challenge value generated at the IC device. The first party then may conduct a software evaluation of the IC device via the debug interface. In response to failing to identify an issue with the IC device from the software evaluation, the first party can permanently enable open access to the debug interface while authenticated and provide the IC device to a second party. Under the direction of the second party, a hardware evaluation of the IC device is conducted via the debug interface that was permanently opened by the first party.

摘要： 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.

摘要： A run-time integrity checking (RTIC) method compatible with memory having at least portions that store data that is changed over time or at least portions configured as virtual memory is provided. For example, the method may comprise storing a table of page entries and accessing the table of page entries by, as an example, an operating system or, as another example, a hypervisor to perform RTIC on memory in which, as an example, an operating system, as another example, a hypervisor, or, as yet another example, application software is stored. The table may, for example, be stored in secure memory or in external memory. The page entry comprises a hash value for the page and a hash valid indicator indicating the validity status of the hash value. The page entry may further comprise a residency indicator indicating a residency status of the memory page.
