Abstract
A method includes providing, by a first electronic device, a first request to a second electronic device for the second electronic device to provide data to the first electronic device representing content that is stored in a security component of the second electronic device. The first electronic device receives the response from the second electronic device to the first request and, in response thereto, the first electronic device stores data in the first electronic device representing content that is stored in a security component of the second electronic device. The method includes performing cross-attestation. Performing the cross-attestation includes, in response to an attestation request that is provided by a verifier to the first electronic device, the first electronic device providing to the verifier data representing content that is stored in the security component of the first electronic device and data representing the content stored in the security component of the second electronic device.
