摘要： The disclosed technology is generally directed to the authentication of software. In one example of the technology, a private attestation key is stored in hardware. In some examples, during a sequential boot process a hash is calculated, in an order in which the software stages are sequentially booted, of each software stage of a plurality of software stages. The hashes of each software stage of the plurality may be cryptographically appended to an accumulation register. The accumulation register may be used to attest to validity of the software stages. The plurality of software stages may include a first bootloader, a runtime for a first core of a multi-core processor, and a runtime for a first execution environment for a second core of the multi-core processor.

摘要： Disclosed herein are system, method, and computer program product embodiments for enabling access to a firmware-locked function of a secure device. A secure device may be production hardware that has locked certain functions not available for public use. In an embodiment, the secure device may receive a request to access a firmware-locked function. The request may include an authorization token that includes an identifier specific to the particular secure device. Based on the receipt of the authorization token, the secure device may retrieve authorization data from the firmware memory of the secure device to determine whether the provided authorization token matches the firmware authorization data. In an embodiment, the secure device may also utilize channel information for authentication purposes. Using the authorization token and/or channel information, the secure device may determine whether to grant access to the firmware-locked function.
