摘要： A method and arrangement is disclosed for flexible control of rendering of protected media comprising first and second content objects. An instruction database combines with traditional use of digital rights objects for determining, at rights parsing and instruction handler, conditions for rendering of first content object. Conditions may force the user to render second content objects or to input requested data and may adapt to environmental conditions exemplary relating to user profile, location, or time of day. A set of second content objects may be pre-determined and specified in provided instructions. User selection, from a list of second content objects, of a specified number of second content objects, provides for generation of a key enabling successful rendering of first content object.

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 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：本发明一般涉及在信息环境中密码密钥世代的管理，包括密钥生成侧生成密钥信息到密钥消耗侧。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的代数之间的关系，使得早期的密钥有效地可以从后者导出，而不是相反地导出。因此，根据本发明的基本思想是通过关键消费侧的新密钥生成的密钥信息来代替关键更新时的老密钥生成的密钥信息。只要有必要，关键消费方迭代地应用预定的单向密钥导出函数，从新密钥生成的密钥信息中导出至少一个较旧密钥生成的密钥信息。以这种方式，可以显着减少关键消费方面的存储要求。

摘要： In a procedure for delivering streaming media, a Client first requests the media from an Order Server. The Order Server authenticates the Client and sends a ticket to the Client. Then, the Client sends the ticket to a Streaming Server. The Streaming Server checks the ticket 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 receives the 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： The invention refers to monitoring usage of digital content provided from a content provider over a network to a client system. In the client system, a logging agent 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, either stored in the client system or at a trusted party. The logged usage information is also authenticated allowing identification of the client using the associated digital content. The entries of the log may include a representation of the content, information about usage quality and/or usage time. The logging agent is preferably implemented in a portable tamper-resistant module, e.g. a network subscriber identity module. The module may be pre-manufactured with the logging agent, or the agent can be downloaded thereto.

摘要： Time critical media (eg television, stock quotes) can be delivered over channels with different delays (eg cable TV network, the internet). Therefore users can play back the media at different times. To ensure that the media is used simultaneously the Service Provider 6 encrypts it (eg using a one time pad pseudorandomly derived from a seed) and delivers it to Media Channel Providers 7, who then deliver it over heterogeneous Media Channels to Receivers 5, where it is buffered. Cryptographic material (eg seed, key) is delivered to Control Channel Providers 8, who forward it to Receivers 5, who use it to decrypt the media. The control channel is selected such that the cryptographic material arrives at all Receivers simultaneously (eg satellite, FM radio, network with QoS). The cryptographic material is transmitted so that it will arrive after the media on the slowest media channel.
