    Abstract: 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.

    Abstract: 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.
