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.

Abstract: Method and cryptographic system for descrambling content packets (15) included within a digital transport stream (10) together with conditional access messages (12) and header data (15') belonging to these content packets (15). This method requires a deciphering algorithm (35), processed by a descrambler (36) of a multimedia unit (30), using an initialization vector (33) as first input and a control word (13) as second input.

Abstract: According to the system and method of the invention a television event may be consumed after been stored in a mass memory of a multimedia unit such as a set top box but still fully relies on the security of a secure device. A conversion of a received content aims at firstly descrambling the content using control words included in entitlement control messages and immediately re-encrypting the descrambled content by a unique key, this key being generated specifically for this content. Access conditions attached to the entitlement control message containing the control word are temporarily stored and once the decryption is terminated, the secure device produces an information block. This information block containing for example access conditions and an identifier of the content is either stored into a secure memory of the secure device or stored in the mass memory with the encrypted content. The unique key is made up of a combination of a root key specific to the secure device and the information block.

Abstract: A method to prevent, detect and fight against cloning attacks by using payload keys to encrypt request and response messages exchanged between user units and server. In an initialization phase, the user unit generates locally an initial payload key and sends to the server in a secure way a request comprising a unique identifier of the user unit, check data, the initial payload key and a request instruction encrypted with a payload key retrieved from the memory of the user unit. Each time the server receives a request from a user unit; it will retrieve the payload key by searching in its memory according to the unique identifier of the user unit. The obtained payload key is then used to decrypt the request instruction. The server then generates a derivation key as response key which will be used by the user unit to compute a new payload key. Doing this way, the payload key is modified preferably during each data exchange between user unit and server, allowing thus the server to check in the next incoming request from the same user unit if the payload key is the expected one. The server also stores a fallback payload key, which is the last one used by the user unit. By checking a status parameter at decryption with the expected payload key or with the fallback key, the server can, by applying predefined business rules, distinguish correct behaviors or authorized user units from unexpected system failures (network, storage, interferences, application software crash, etc.) and from true cloning attacks.

Abstract: A method for monitoring an execution of a sequence of instructions of a data processing program (PR) in a security module (SM) associated to a multimedia unit (MU) connected to a managing center (MC) supplying control messages (ECM, EMM) authorizing the multimedia unit (MU) to access broadcast audio video content data streams. The security module (SM) comprises at least one processor (CPU) executing the data processing program instructions, a memory (M), and a monitoring module (MM) for analyzing the instructions before execution by the processor (CPU). The managing center (MC) comprises a security module emulator (EM) generating reference data sets (REF) by executing a sequence of instructions induced by data of a given control message (ECM, EMM) in the data processing program (PR). The reference data sets (REF) are appended to control messages (ECM, EMM) sent to the security module (SM) for verification. The monitoring module (MM) analyses a sequence of instructions of the data processing program (PR) for determining a check data set (CD) which is compared with a reference data set (REF) received from the control messages (ECM, EMM). When the reference data set (REF) matches with the check data set (CD), the data processing program (PR) continues its execution. Otherwise, the monitoring module (MM) sends an instruction (INT) to the processor (CPU) preventing further processing of the control messages (ECM, EMM) by the security module (SM).
