Abstract: Techniques are disclosed relating to biometric authentication. In one embodiment, a computing device includes a controller circuit, a camera, and a secure circuit. The controller circuit is coupled to a button and detects when the button has been pressed. The camera captures a set of biometric data of a user. The secure circuit performs an authentication of the user by confirming that a notification identifying the button being pressed was received from the controller circuit and by comparing the set of biometric data with another set of biometric data for an authorized user of the computing device. In some embodiments, the controller circuit is configured to maintain a timestamp indicative of when the button has been pressed and usable by the secure circuit to confirm that the button is pressed within a threshold time period of the authentication being performed.

Abstract: Techniques are disclosed relating to relating to a public key infrastructure (PKI). In one embodiment, an integrated circuit is disclosed that includes at least one processor and a secure circuit isolated from access by the processor except through a mailbox mechanism. In some embodiments, the secure circuit is configured to generate a public key and a private key for an application, and receive, from the application via an API, a request to perform a cryptographic operation using the private key. The secure circuit is further configured to perform the cryptographic operation in response to the request.
