Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory or storage device) for a session-based encryption (e.g., a common-tier encryption) for delivering a content (e.g., video, data, multi-media content and the like) on demand using multiple encryptors. According to an embodiment, the STB's request for a VOD session may be routed by a session resource manager (SRM) to receive content from an appropriate encryptor chosen from multiple encryptors based on a predefined criteria. This approach can minimize a number of encryptions/encryption devices (such as ECM generators) needed in a cable network. However, the simulcrypt encryptor can be also used, if necessary, e.g., when CAS-only encryptors are fully loaded with a traffic.

Abstract: Techniques for pairing two different security modules that use two different encryption technologies for operation in two different networks include generation and transmission of a secret to both the security modules via their respective communication networks. In one advantageous aspect, one of the security module, which may be prone for duplication or theft, is logically tethered to the other security module via the pairing. For example, after pairing is successfully performed, the first security module may be usable in a wide area network only when its presence in a local communication connection, such as a home network of a subscriber, or a peer-to-peer or a near field communication link, can be detected and verified by the second security module.

Abstract: Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

Abstract: The aim of the present invention is to ensure that a security module or conditional access module ("module") is used together with an authorised receiver/decoder to access pay TV content. The module uses a wireless transceiver to read an authorisation message from a wireless tag attached to the receiver/decoder to which it is connected. The authorisation message contains an identifier of the module and is encrypted with a system key. If the obtained identifier in the authorisation message is not the one of the security module, operation of the security module is blocked. The authorisation message is written by a communications device (located i.e. in a shop selling receiver/decoder devices) to a wireless tag attached to the receiver/decoder. Thus a sold receiver/decoder can be immediately operated together with a specific module.
