摘要： A method, apparatus, and/or system are provided for establishing trust between an accessory device and a host device, using a global key known to both the host device and the accessory device, so that content protection for subscriber-based mobile broadcast services is provided. A secure link may be established between the accessory device and the host device so that when the accessory device receives encrypted content via a secured forward link only network, the accessory device may decrypt the content at the forward link only stack. The content is then re-encrypted/re-secured using one or more derived encryption keys and then sent to the host device where it may be decrypted and played back. A global key, unique to the particular device type of the host device, is employed to ultimately derive the session encryption keys used to re-encrypt/re-secure the content conveyed from the accessory device to the host device.

摘要： 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.
摘要翻译： 在本系统中，提供三种方法用于在附件设备和主机设备之间建立信任，而不对设备/主机所有者进行信任，从而提供对基于订户的移动广播服务的内容保护。 也就是说，可以在附件设备和主机设备之间建立安全链路，因此当附件设备经由仅前向链路网络接收加密的内容时，附件设备可以在前向链路堆栈处解密内容，然后重新加密 或者使用主密钥或基于主密钥（或会话密钥）的其他派生密钥重新安全，然后将其发送到可以解密的主机设备回放。

摘要： A method and/or apparatus are provided for protecting control information during broadcasts in a system where primary and second mobile broadcast control messages (PMBCM and SMBCM) are utilized. In order to protect the SMBCM, a first hash information instance is computed based on hashes for each a plurality of control data blocks for the SMBCM. The first hash information instance is appended to the PMBCM. Error-correcting code words are generated for the plurality of hashes for the plurality of control data blocks for the SMBCM. These error-correcting code words are appended to the control data blocks of the SMBCM. A receiver uses the first hash instance information in the PMBCM to determine if any control data blocks of the SMBCM are corrupt. If so, the error-correcting code words may be used to reconstruct the corrupted hash(es) for the control data block(s) in order to authenticate the remaining control data blocks.
