摘要： A method of transferring a content license (L2) to a first device (10) from a second device (20). The second device (20) renders (202) the license (L2) unusable to itself and sends (208) this license ([L2]) to the first device (10) that verifies (214) that it may import the license ([L2]) which is the case if it has rendered one of its own licenses ([L1]) unusable to it, but has not exported this license ([L1]). If so, it updates (216) its license information (F1) so that it may import one license less and makes (218) the received license usable. The first device (10) also receives a content file (S2) that corresponds to the received license. The invention enables flexible transfer of licenses, as e.g. the second device (20) may export the license to the first device (10) without receiving anything in return, but the exportation does provide it with the right to import a further license. Also provided is a device.

摘要： A method and device for device association. A user (150) enters (200) login and password on a first device (110) that searches (210) for reachable devices (120, 130). The first device (110) asks (220) the reachable devices (120, 130) if they know the login, preferably by sending a salted hash of the login. The devices that know the login respond positively and the first device (110) lists (230) the responding devices. The first device (110) then successively performs (240) Secure Remote Authentication (SRP) with each device on the list until an authentication succeeds or there are no further devices on the list. The SRP authentication makes sure that the first device (110) knows the login and that the other device knows a password verifier without transmitting any knowledge that allows recuperation of this info by an eavesdropper. The authenticated devices then establish (260) a secure channel over which a community secret key is transferred (280), and the first device also calculates and stores (270) the password verifier.

摘要： The invention concerns a method for recording digital data (ETK(C), SDKS, EDK(TK)) on a blank disc with a client device, the digital data being transmitted to the client device by a remote content server. The method includes the following steps performed on the client device: setting up (82) a secure authenticated channel (SAC) with the content server; receiving (84) the digital data (ETK(C), SDKS, EDK(TK)) transmitted by the content server; verifying (86) the existence of the secure authenticated channel (SAC) and authorizing the recording of the digital data (ETK(C), SDKS, EDK(TK)) received exclusively during the presence of the secure authenticated channel (SAC); and recording (88) on the blank disc the received digital data (ETK(C), SDKS, EDK(TK)). The invention also concerns a client device and a method for distributing digital data.

摘要： A method for controlling distribution of licenses (251; 351), a license being for an excerpt (252; 352) of a content item (211; 311), the content item comprising a set (100) of continuous units (110), each excerpt (252; 352) comprising a subset of the set (100) of continuous units. A device (230; 340) receives an identifier of a receiver (230; 330) of a license, and the license (251) or a request (322) to generate the license (351), the license or the request (322) to generate the license (351) comprising a content identifier and at least one indicator of the units covered by the license (251; 351); retrieves stored information regarding licenses previously delivered to the receiver; compares a limit value for the content item with the stored information combined with information from the license or the request (322) to generate the license (351); and allows the receiver access to the license only if the limit value is not exceeded by the stored information combined with information from the license or the request (322) to generate the license (351). Also provided is the device (230; 340).

摘要： A system for distribution of a content item (130) in a network (200), particularly a peer-to-peer network. A requesting node (210B-210D) sends a request for the content item (130). An access requirement value for the content item is compared to a counter value for the requesting node (210B-210D) to determine if the requesting node may download the content item (130) from a sharing node (210A). The counter value is advantageously linked to the requesting node's habit of sharing content items. The access requirement value, which preferably is not only linked to the size of the content item, is modified for at least one content item (130) in the network (200), either following a time rule or when the content is downloaded. In this way it can be ensured that initial downloaders are likely to share the content item and that the content then gets more accessible to other nodes. Also provided are a sharing node (210A), a server (600) and a method.

摘要： In order to provide a secure measurement of Round Trip Time (RTT), the calculation of RTT and the authentication data are separated. A device A (212) sends a message (222) to device B (216) to start the method. Both devices generate (224; 226) a random number (Random_A, Random_B) and device A waits (228) for device B to finish. Device A sends (242) its random number to B, which answers (246) with its own random number, and device A calculates (250) the RTT. If the RTT is below a certain limit, device A then requires (252) authentication data, which is calculated (262) by device B and sent (264) to device A that verifies (266) the authentication data. The RTT can thus be securely calculated regardless of the calculating resources of device B. Alternate embodiments, a system and devices are also provided.
