Abstract
A host receiver and a client receiver are operatively in a direct broadcast satellite system. Program materials received by the host receiver from the direct broadcast satellite system are decrypted by the host receiver. The decrypted program materials are then encrypted at the host receiver using a copy protection key. The copy protection key is encrypted at the host receiver using a host-client pairing key shared between the host receiver and client receiver. The encrypted program materials and the encrypted copy protection key are transferred from the host receiver to the client receiver. The transferred copy protection key is decrypted at the client receiver using the host-client pairing key. The transferred program materials are then decrypted at the client receiver using the decrypted copy protection key.
