摘要： A method of processing digital content according to a workflow. The digital content is received and information for the workflow is checked to decide if a processing device is authorised to process the content, the workflow imposing that the digital content be processed in a process chain comprising at least two nodes, wherein the processing device is authorised to process the content if it corresponds to the node that according to the process chain is the next node to process the digital content. If the processing device is authorised to process the content, the digital content is processed and the information for the workflow is updated. Also provided is a system.

摘要： To access services on a device, such as a computer, a user has a portable device in two parts: a plug adapted to be inserted in a USB port and a transponder that remains about his person. In a preferred embodiment, an access manager verifies that first the plug and then the transponder are identified. If so, the access manager verifies if plug and transponder have to be paired and if they have the proper access rights for the desired service. Only then is access given. In a further embodiment, more than one transponder is needed to access a certain service. It can thus be appreciated that the invention provides a flexible and secure way to secure access to services.
摘要翻译：为了访问诸如计算机的设备上的服务，用户具有两部分的便携式设备：适于插入USB端口的插头和保持在他的人身上的应答器。在优选实施例中，访问管理器首先验证插头然后识别应答器。如果是这样，访问管理器验证插头和转发器是否必须配对，并且是否具有所需服务的正确访问权限。只有这样才能获得访问权限。在另一实施例中，需要多于一个应答器来访问特定服务。因此可以理解，本发明提供了一种灵活和安全的方式来确保对服务的访问。

摘要： The present invention concerns a method and a device for encrypting an encoded scalable enhancement frame sent by an emitter to a receiver, the enhancement frame comprising a plurality of complementary streams ordered in term of quality level, each complementary stream corresponding to a combination of more than one scalability type, where a complementary stream of a lower quality level corresponds to a lower quality on each scalability type, comprising at the level of the emitter the steps of generating a key per complementary stream for encrypting said complementary stream in such a way that all scalability types can be either simultaneously or individually used, said keys being generated in such a way that only the keys of the complementary streams of quality levels lower than the quality level of a complementary stream can be obtained from the key of said complementary stream, and sending the key of a complementary stream corresponding to a required quality level to the receiver, the key permitting a receiver to generate the keys of the complementary streams of the lower quality levels only. The present invention also concerns a method and a device for decrypting a received encoded scalable enhancement frame.

摘要： The invention relates to pairing a slave device with a master device, for example decoders in a conditional access system. There is provided a security module that stores a device state that indicates whether a decoder shall be a master or a slave decoder. There is also provided a method in a conditional access system of providing a device with a device state stored on a security module. It is detected that the security module is in connection with the device and the device state is transferred from the security module to the device. There is further provided a method of pairing a slave device with a master device. The slave device asks the master device to identify itself, the master device returns an identification, and if the slave device has not yet been paired with a master device, it checks the identity of the master device and, if the identity is verified pairs with the master device. There is also provided a first, slave, device for pairing with a second, master, device. The first device comprises an interface for sending an identification command to and receiving an identification message from the master device, and a processor for checking the identity of the second device and pairing the first device with the second device.

摘要： The invention relates to a process for controlling digital rights of the “Play N times” type for a digital audio and/or video content (132), referred to as controlled content (132), the controlled content being consumed by a consumer on a consuming device (112) or on another device delegating the controlling of these rights to the consuming device. According to the invention, such a process is characterized in that charging of one additional usage is inhibited in at least one of the following cases where: the consumer momentarily consumes another content, on the same device (112) where the controlled content (132) is consumed, and then returns to the controlled content (132), the consumer effects a pause in the usage of the controlled content (132), the consumer performs a fast-forward of the controlled content (132), the consumer performs a rewind of the controlled content (132).

摘要： A method for secure installation of software applications. The user receives the software, partly encrypted, and an installation token for a number of licenses from the software provider, plugs the software and the installation token into a computer, and launches the installation application. A Secure Authenticated Channel is established between the installation application and the installation token and a unique identifier of the computer is sent thereon to the installation token. The installation token verifies that there are remaining licenses, decreases the remaining licenses, authorizes the installation and sends the decryption key and a certificate/key pair to the installation application that decrypts and installs the software, preferably linking the installation to the computer's identifier. A variant allows (virtually) unlimited installations of time limited programs that are transformed into time unlimited programs once the installation token has reported the number to the software provider and paid for the necessary licenses. Also provided is the installation token.

摘要： The invention relates to a method whereby it can be checked whether data received by a receiver has been sent by a transmitter authorized by a trusted third party, the transmitter and the receiver being connected to a digital network. An identifier is associated with the data sent by the transmitter and, on receipt of the data by the receiver, the receiver generates a random number and diffuses the same on the network. The transmitter that receives said random number calculates a response by applying a first function to the random number and to the identifier, and sends said response to the receiver which verifies the response received by applying a second function to the response received, the random number and the identifier. The first function is delivered first to the transmitter by the trusted third part, and the second function is a function for checking the result of the first function which is delivered first to the receiver by the thrusted third party.

摘要： A method for discovering emulated clients. A verifier sends a cryptographic challenge C to a client and preferably starts a timer. The client uses a deterministic key search algorithm to find the correct key and returns the result as a number of tries needed. The verifier then stops the timer if this was started and verifies that the result is correct and preferably that the response was timely. Also provided is a verifier.
