    摘要: Digital rights management is described involving a device, a content issuer, and a rights issuer. A content encryption key (CEK) is encrypted using a public key associated with the device to produce an encrypted CEK. The encrypted CEK is encrypted using an issuer encryption key to produce a twice encrypted CEK. The twice encrypted CEK is encrypted using the public key to produce a ciphertext included in a rights object. The rights object is available to the device for decrypting digital content associated with the content issuer. The device can then decrypt the rights object ciphertext using its private key to produce a decrypted rights object ciphertext and decrypt the decrypted rights object ciphertext using an issuer decryption key received from the content issuer to produce an encrypted CEK. The encrypted CEK is decrypted using the private key to obtain the CEK, which is then available for decrypting digital content.

    摘要: Disclosed is a method and a system for rendering content on external devices securely. The method comprises setting up a communication channel between a proxy rendering server of a mobile device and an external rendering server of an external device, authenticating at least the external rendering server and upon successful authentication transferring a key from the proxy rendering server to the external rendering server, transferring the content encrypted with the transferred key from the proxy rendering server to the external rendering server for rendering the content, wherein the rendering of the content is performed in one of two modes, either in a preprocessing mode or in a non-preprocessing mode, and wherein a DRM agent is only present in the mobile device.

    摘要: Methods and apparatus for securely streaming multimedia packets, such as RTP packets, are disclosed, in which the payloads of the packets are shuffled. This reordering is performed using a shuffling function that depends on sequence numbers associated with each of the packets, a pre-determined group size N, and a pre-determined initialization value; in some embodiments this shuffling function comprises a cryptographic hashing function or other one-way function. A receiving device may reverse the shuffling, using a similar shuffling function, if the pre-determined group size N and the pre-determined initialization value are known.

    摘要: An input device for an electronic device such as a mobile phone includes an analog input device for scanning through an input space of records and a digital input device for selecting a current record presented on a display. The analog input device is a flip pivotably arranged by an attachment device on a housing of the electronic device. The attachment device is provided with a rotational sensor device connected to a processing device incorporated in the housing. An angle between the flip and the housing corresponds to a sensor value, translated and interpreted by the processing device, to show a particular record on the display.
