摘要： A method for achieving a secure recording and storing of a recorded activity is based on an extended Digital Rights Management (DRM) system. A recording and storing procedure is initiated, in response to recognising one or more triggers (202) at a device (201) hosted by a user equipment (200a, 200b). On the basis of the one or more triggers a Rights Issuer (204,RI) is located, and a Recording and Storing Instruction (RSI) is retrieved from the RI, using an existing DRM standard. Based on the RSI, a trusted storage for storing the recorded activity is located, and one or more recording procedures, involving one or more recording equipments, are activated and managed (2:5) by the device. Before the recorded content is forwarded (2:6) to the trusted storage, a protected content is generated from the recorded content, according to content of the RSI.

摘要： The invention refers to monitoring usage of digital content provided from a content provider (30) over a network (40) to a client system (10). In the client system (10), a logging agent (150) generates and stores information concerning usage of the digital content individually for each usage to be monitored. The generated information is entered in a usage log (170; 175), either stored in the client system (10) or at a trusted party. The logged usage information is also authenticated allowing identification of the client using the associated digital content. The entries (172) of the log (170; 175) may include a representation (172-1) of the content, information about usage quality (172-2) and/or usage time (172-N). The logging agent (150) is preferably implemented in a portable tamper-resistant module (400), e.g. a network subscriber identity module. The module (400) may be pre-manufactured with the logging agent (150), or the agent (150) can be downloaded thereto.

摘要： A method and arrangement in a first mobile terminal (600) for determining allocation of radio resources for DMO communication amongst a group of mobile terminals. M the first mobile terminal, a first determining module 600a determines a communication (Sout, Sin) with a second mobile terminal (602) of the group. A second determining module (600b) determines a resource element (RE) for communication by applying a predefined cryptographic function Pbased on a terminal identification (K)). Tne cryptographic function has been configured in the mobile terminals of the group to provide terminal-specific resource elements for different mobile terminals within respective radio frames. A communication module (600c) then communicates with the second mobile terminal (602), either by transmission or reception of the data, on the determined resource element (RE).

摘要： The invention concerns a tamper-resistant electronic circuit (10) configured for implementation in a device (100). The electronic circuit (10) securely implements and utilizes device-specific security data during operation in the device (100), and is basically provided with a tamper-resistantly stored secret (C) not accessible over an external circuit interface. The electronic circuit (10) is also provided with functionality (13) for performing cryptographic processing at least partly in response to the stored secret to generate an instance of device-specific security data that is internally confined within said electronic circuit (10) during usage of the device (100). The electronic circuit (10) is further configured for performing one or more security-related operations or algorithms (14) in response to the internally confined device-specific security data. In this way, secure implementation and utilization device-specific security data for security purposes can be effectively accomplished. The security is uncompromised since the stored secret (C) is never available outside the electronic circuit, and the device-specific security data is internally confined within the circuit during usage or operation of the device.

摘要： The present invention aims at an effective approach to radio access system attachment in a heterogeneous communication network environment. According to the present invention, cooperation between different radio access systems (10, 12) is executed to advertise one radio access system in another. After receipt of a secure advertisement from a control unit (16) of the advertising radio access system (12), a broadcasting unit of the receiving radio access system broadcasts advertisement information in relation to the secure advertisement in the communication network. Therefore, according to the present invention, a user terminal (20) may at any time receive broadcasted advertisement information while establishing a trusted relationship with advertiser.

摘要： The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.
摘要翻译：本发明总体上涉及信息环境中的密码密钥世代的管理，该信息环境包括产生密钥信息并将密钥信息分发给密钥消费端的密钥产生端。本发明的基本概念是通过预定的单向密钥导出函数来定义密钥生成之间的关系，以使得可以从较晚的密钥有效地导出较早的密钥世代，而不是以其他方式导出密钥。因此，根据本发明的基本思想是在密钥更新处将旧密钥生成的密钥信息替换为密钥消费侧的新密钥生成的密钥信息。在必要时，密钥消费方迭代地应用预定单向密钥导出函数以从新密钥生成的密钥信息导出至少一个较旧密钥代的密钥信息。通过这种方式，可以显着减少关键消费方的存储需求。

摘要： In a procedure for delivering streaming media, a Client (1) first requests the media from an Order Server (3). The Order Server authenticates the Client and sends a ticket to the Client. Then, the Client sends the ticket to a Streaming Server (5). The Streaming Server checks theticket for validity and if found valid encrypts the streaming data using a standardized real-time protocol such as the SRTP and transmits the encrypted data to the Client. The Client receivesthe data and decrypts them. Copyrighted material adapted to streaming can be securely delivered to the Client. The robust protocol used is very well suited for in particular wireless clients and similar devices having a low capacity such as cellular telephones and PDAs.

摘要： In a method of enabling Digital Rights Management (DRM) of content in a communications network supporting a DRM system a first user equipment (RMUE), is registering with a first rights issuer of the DRM system from which a delegation assertion, authorizing the RMUE to become a private rights issuer, is retrieved. RMUE retrieves a first, signed rights object from the first rights issuer, that contains a first set of rights for the RMUE to DRM protect private content and to issue at least one second rights object, associated with the private content. DRM protection is then applied on private content, obtained by the RMUE, according to at least the first set of rights. RMUE issues a second rights object, defining a second set of rights for rendering the private content, according to the first set of rights. RMUE may then distribute the second rights object to a second user equipment which is able to render the private content on the basis of at least said second rights object, upon having acquired the private content and the delegate assertion.

摘要： A method and apparatus for distributing time-controlled media. A media chunk is encrypted using cryptographic materials and sending the encrypted media chunk over a media channel. The cryptographic materials are distributed over a time-guaranteed control channel such that the cryptographic materials are received by a remote receiver node after the remote receiver receives the encrypted media chunk. The receiver node receives the encrypted media chunk over the media channel and stores the encrypted media chunk in a memory at the receiver node. The receiver node also receives the cryptographic materials over the time guaranteed channel, and uses the cryptographic materials to decrypt the encrypted media chunk. In this way, the receiver node cannot render the media chunk until it has received the cryptographic materials.
