Abstract
A technique for securely transferring content from a first device in a first layer to a second device in a second layer. In one embodiment, the first device is a device in a trusted domain and the second device is outside of the trusted domain. Transfer of protected content to another device may require authentication of the receiving device. A rights file which specifies the rights of the receiving device to use the protected content, according to its security level is also transferred. These rights may concern, e.g., the number of times the receiving device may transfer the protected content to other devices, the time period within which the receiving device may play the protected content, etc. The higher the security level of the receiving device, the more rights accorded thereto. A minimum security level requirement may be imposed in order for protected content to be transferred to a device.
