Abstract
Disclosed is a manufacturing process and feature licensing system for provisioning personalized (device-unique) licenses to devices, with the following characteristics. The system is secure in that it uses a secure key wrapping mechanism to deliver the LSK to LPS. Another feature is that various network communication links are secured using standard security protocol. Further, application messages, license templates, licenses are digitally signed. The system is also flexible because it is configured to allow multiple manufacturers and to allow various feature configurations via the use of License Template. The system is also scalable, as it is possible to use multiple LPS hosts to serve multiple programming stations. The system is available in that the delegation of license signing capability from CLS to LPS eliminates the dependency on unreliable Internet connections. Redundant LPS hosts provide high level of availability required for high volume license provisioning.
