摘要： A method is provided for enhancing security of a communication session between first and second endpoints which employs a key management protocol. The method includes sending a first message to a first end point over a communications network requesting a secure communication session therewith. The message includes an identity of a second end point requesting the authenticated communication session. A digital certificate is received from the first endpoint over the communications network. The digital certificate is issued by a certifying source verifying information contained in the digital certificate. The digital certificate includes a plurality of fields, one or more of which are transformed in accordance with a transformation algorithm. A reverse transform is applied to the one or more transformed fields to obtain the one or more fields.

摘要： Disclosed is a manufacturing process and feature licensing system for provisioning personalized (device-unique) licenses to devices. The secure system 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. Application messages, license templates, licenses are digitally signed. The system is flexible, configured to allow multiple manufacturers and to allow various feature configurations via the use of License Template; scalable, as it is possible to use multiple LPS hosts to serve multiple programming stations; and 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. The system is traceable: license and device association are replicated back to the CLS to provide full license request and generation traceability.
