Abstract

See full text

A device with key attestation features comprises an operating system stored in its memory, the operating system comprising a secure environment including a trusted application, and two or more device certificates, each associated with a device key pair, stored in the memory of the device. The trusted application is configured to handle key pair generation requests and key pair attestation requests to read an indication of a preferred device certificate. An attestation certificate that is generated in response to the key pair attestation request is then signed using one of the two or more device certificates with its associated device key pair based on the indication of a preferred device certificate.
