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来的密钥导出，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： 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 system, method and transcoding proxy are described herein that are capable of transcoding encrypted content, like an encrypted multimedia message or a multimedia message containing encrypted elements parts, which is transmitted between two devices (e.g., mobile phones). Basically, the transcoding proxy receives an encrypted multimedia message from a first device (e.g., mobile phone). The transcoding proxy then requests and receives a transcoding rights object (TRO) message from a rights issuer which includes a content encryption key (CEK) and a transcoding permission message (optional). After receiving the TRO message, the transcoding proxy is able to (1) decrypt the encrypted multimedia message (2) transcode the decrypted multimedia message so it matches the capabilities of a second device and could be accessed by a user of the second device (e.g., mobile phone) and (3) re-encrypt the transcoded multimedia message. The transcoding proxy then sends the re-encrypted transcoded multimedia message to the second device.

摘要： A tamper-resistant electronic circuit is configured for implementation in a device. The electronic circuit securely implements and utilizes device-specific security data during operation in the device, and is basically provided with a tamper-resistantly stored secret not accessible over an external circuit interface. The electronic circuit is also provided with functionality 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 during usage of the device. The electronic circuit is further configured for performing one or more security-related operations or algorithms 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 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： 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： Devices for providing flexible control of rendering of protected media comprising first and second content objects are provided. 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.
