Abstract:
A method and system of enforcing a computer policy uses a central server to manage user profiles, policies and encryption keys. The server securely supplies the keys to client devices only after checking that the policy has been complied with. The checks include both the identity of the user and the machine identity of the client device. The keys are held in a secure environment of the client device, for example in a Trusted Platform Module (TPM), and remain inaccessible at all times to the end user. Theft or loss of a portable client device does not result in any encrypted data being compromised since the keys needed to decrypt that data are not extractable from the secure environment.

Claim (Index 19):
The system of  claim 16 , wherein the client device comprises a hardware security module, and wherein the server is configured to authenticate the client device by requesting the hardware security module on the client device to compute a signature using a private key belonging to the hardware security module.
