Abstract
A computer or other electronic device uses a cryptographic capability and hardware identifier to verify a provisioning packet for changing the mode of operation of the device or a licensed component. A secure memory stores the provisioning packet for future reference. A sequence number may be used to limit replay attacks. An exemplary use is conversion of a computer from metered use during a subscription period to unlimited use when the subscription terms have been satisfied.
