| description | An encryption scheme is provided between a device that communicates material content and the intended receiver of this content. The encryption is applied to a ticket that conveys copy and display rights. To allow for the portability of devices, the encryption scheme in a preferred embodiment is dynamic. At any point in time, the channel between the providing device and the receiving device is configured for the exclusive use of these two devices; thereafter, the channel may be configured for the exclusive use of another set of devices. To prevent the use of non-conforming devices within the system, conforming devices contain verifiable certificates of authenticity, and channels are established when each device on the channel verifies the other device's authenticity. |
