    摘要: A method for generating a compressed RSA modulus, allowing up to two thirds of the bits of a modulus N to be fixed. N has a predetermined portion NH, which comprises two parts Nh and Nm. A candidate RSA modulus that shares the Nh part is generated, and the candidate is then modified using Euclidian-type computations until it shares both Nh and Nm. Also provided is an apparatus for calculating compressed RSA moduli according to the method and a computer program product.

    摘要: A content server maintains a database of different content files, these files being scrambled by control words that are stored in a database. The control words are necessary for descrambling the content files. When a device requests a content file, it sends a public key to the content server, along with the request. The content server encrypts the control words with the public key and transmits both the ciphered control words and the scrambled content file to the device. In one embodiment, the device decrypts the control words, and, when a further device on the home network requests a content file, sends the scrambled content file, along with the necessary control words encrypted with a local key that may have been provided by the further device.

    摘要: The invention relates to a method for controlling digital rights of the “Play N times” type for a digital audio and/or video content, referred to as controlled content, the controlled content being consumed by a consumer on a consuming device or on another device delegating the controlling of these rights to the consuming device. According to this method, 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 where the controlled content is consumed, and then returns to the controlled content; the consumer effects a pause in the usage of the controlled content; the consumer performs a fast-forward of the controlled content; or the consumer performs a rewind of the controlled content.

    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: A cartridge preferably for use with a game console. The cartridge comprises a ROM, a non-volatile memory, a processor and a dispatcher. An application running on the console may communicate with the dispatcher using predefined addresses, which enables the dispatcher to access the ROM, the non-volatile memory, or the processor, as the case may be. The invention improves on the prior art copy protection as no generic copy method may be found if the addresses are changed from one cartridge to another. In addition, to copy the software, the processor must be emulated.

    摘要: The invention relates to a method to verify that 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 the random number calculates a response by applying a first function to the random number and to the identifier, and sends the 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 party. The second function is a function for checking the result of the first function which is delivered first to the receiver by the trusted third party.
