In the present system three methods are provided for establishing trust between an accessory device and a host device, without placing trust in the device/host owner, so that content protection for subscriber-based mobile broadcast services is provided. That is, a secure link may be established between the accessory device and the host device so when the accessory device receives encrypted content via a forward link only network, the accessory device may decrypt the content at the forward link only stack and then re-encrypt it or re-secure it using the master key or some other derived key based on the master key (or the session key) and then send it to the host device which can decrypt it play it back.
