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： 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： A device receives protected content and a license for the content, unprotects the content using an input key and retrieves a rule associated with the input key. The device then processes the content to create new content, retrieves at least one output key associated with the input key in the retrieved rule, protects the content using the output key and sends the newly protected content and the corresponding license. It is thus possible to impose a work flow as it is necessary for a device to store a particular key in order to access the content and as the rule imposes a particular output key depending on the input key. In a preferred embodiment, the content is scrambled using a symmetrical key that is encrypted by an asymmetrical key in the license. An alternate embodiment uses watermarking techniques instead of encryption. The invention finds particular use in video processing.

摘要： A distributed communication and data sharing system that provides anonymity and unlinkability. A group comprising a number of structures, each having a public/private key pair, is stored on a plurality of nodes in a Distributed Hash Table. Advantageous features of the group management system are provided through the use of Cryptographically Generated Addresses (CGA) for the structures, a secure capture method that enables a user to capture an address and be the only one authorized to request certain operations for the address, and an anonymous get/set mechanism in which a user signs messages, encloses the public key in the message and encrypts the message and public key using the public key of the receiver. The distributed communication and data sharing system of the invention can advantageously be used for group management of social networks.

摘要： A method for fingerprinting wireless devices and a method for using a device fingerprint for identifying wireless devices. A monitoring station listens to a channel. For each received frame, the station measures the inter-arrival time from the end of the previously received frame to the end of the present frame, If possible, the station obtains the identity of the sender of the frame. If the sender is known, then the station stores the inter-arrival time in a histogram for the sender; the histogram becomes the fingerprint for the sender. Identification of a device begins by obtaining a number of inter-arrival times for an unknown sender and then matching these to stored fingerprints using a suitable similarity measure. The invention is particularly suitable for IEEE 802.11 and may for example be used to detect so-called MAC spoofing and as an additional layer of an identification protocol.
摘要翻译：一种无线设备的指纹识别方法以及使用设备指纹识别无线设备的方法。一个监听站监听一个频道。对于每个接收的帧，站测量从先前接收的帧的结束到当前帧的结束的到达之间的时间。如果可能，站获得帧的发送者的身份。如果发送者是已知的，则该站将发往者的到达时间存储在直方图中; 直方图成为发送者的指纹。设备的识别开始于通过获得未知发送者的到达之间的时间数目，然后使用合适的相似度度量将它们与存储的指纹进行匹配。本发明特别适合于IEEE 802.11，并且可以例如用于检测所谓的MAC欺骗和作为识别协议的附加层。
