MECHANISM FOR ENFORCING USER-SPECIFIC AND DEVICE-SPECIFIC SECURITY CONSTRAINTS IN AN ISOLATED EXECUTION ENVIRONMENT ON A DEVICE

摘要

A method and system for receiving from an authenticated user, at an authorization server, via a service provider, an authorization request to perform a sensitive operation on a first device. The method also includes generating, by the authorization server and in response to receiving the authorization request, an authorization token that includes a device constraint and a binding code constraint, which includes a binding code. Additionally, the method includes transmitting the authorization token to an isolated execution environment of the first device, where the sensitive operation is not permitted on the first device unless the first device successfully performs a verification in the isolated execution environment using the authorization token. Furthermore, the method includes permitting the sensitive operation based on the verification.
