Abstract
Certain embodiments disclosed herein provide attestation for a transient version of an application while reusing the attestation and the cryptographic key on which the attestation is based for the full version of the application should the user obtain the full version of the application prior to the transient version being deleted. As an example, a computing device can detect an upgrade event corresponding to replacing an application clip with the full version of the application, and associate the cryptographic key already stored in a key database with the full version of the application. Associating the existing key with the full version of the application enables the full application to automatically take over the attestation previously provided for the application clip, saving time and resources that would otherwise be used for establishing a new attestation for the full version of the application.
