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.
摘要翻译：用于实现记录活动的安全记录和存储的方法基于扩展的数字版权管理（DRM）系统。响应于识别由用户设备（200a，200b）托管的设备（201）处的一个或多个触发器（202），启动记录和存储过程。基于权利人（204，RI）所在的一个或多个触发器，并且使用现有DRM标准从RI检索记录和存储指令（RSI）。基于RSI，存储用于存储记录的活动的信任存储器，并且由设备激活和管理涉及一个或多个记录设备的一个或多个记录过程（2:5）。在记录的内容被转发（2：6）到可信存储之前，根据RSI的内容，从记录的内容生成受保护的内容。

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： 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.
摘要翻译：一种用于分发时间控制媒体的方法和装置。使用加密材料加密媒体块，并通过媒体信道发送加密的媒体块。加密材料通过时间保证的控制信道分布，使得密码材料在远程接收器接收到加密的媒体块之后由远程接收器节点接收。接收机节点通过媒体信道接收加密的媒体块，并将加密的媒体块存储在接收机节点的存储器中。接收器节点还在时间保证信道上接收加密材料，并使用加密材料解密加密的媒体块。以这种方式，接收器节点在接收到加密材料之前不能呈现媒体块。
