摘要： Methods and apparatus for protecting copyrighted information, e.g., video signals, from unauthorized use are described. Encrypted video signals are transmitted from a source device, e.g., display adapter, to a display device, e.g., monitor, over analog signal lines after the identity of the destination device is confirmed by receipt of a certificate assigned to the destination device. A session key, used for encrypting the analog signals, is generated and exchanged between the source and destination devices. The source and destination devices each include a pseudo-random number generator driven by the session key. As part of the encryption process a false video signal is generated. The false video signal and R, G, B video signals are transmitted to the display device over four lines. The lines used to transmit the R, G, B and false video signals are periodically swapped as a function of the output of the pseudo random number generator to encrypt, e.g., scramble, the video signals. To avoid having to provide an additional line between the display adapter and the display device beyond those used in conventional displays, horizontal synchronization information is combined with, e.g., modulated on, one or more of the other signals transmitted to the display. The horizontal sync line is then used to convey one of the four video signals. The display device extracts the horizontal timing information from the received video signals and decrypts the signals using the output of its pseudo random number generator to reverse the scrambling process used to encrypt the transmitted video signals.

摘要： Methods and apparatus for protecting copyrighted information, e.g., video signals, from unauthorized copying. Analog red (R), green (G) and blue (B) video signals are transmitted from a source device, e.g., a display adapter, to a display device, e.g., a monitor, over corresponding analog signal lines after the identify of the destination device is confirmed by receipt of a certificate assigned to the destination device. A session key, used for encrypting the analog signals, is generated and exchanged between the source and destination devices after the identification of the destination device is confirmed. The source and destination devices each includes a pseudo-random number generator driven by the session key. The lines that carry the R, G and B video signals are changed, e.g., swapped, on a periodic basis as a function of the output of the pseudo-random number generator in the source device. The destination device, which has an input to its pseudo-random number generator synchronized with the random number generator of the source device, decrypts the received video signals in a complimentary fashion to the encryption. Encrypted digital information subject to copying constraints may be supplied to a display adapter via an IEEE 1394 compliant bus.

摘要： Techniques are disclosed to enable utilization of randomly-occurring features of a label (whether embedded or naturally inherent) to provide counterfeit-resistant and/or tamper-resistant labels. More specifically, labels including randomly-occurring features are scanned to determine the labels' features. The information from the scan is utilized to provide identifying indicia which uniquely identifies each label and may be later verified against the label features that are present to determine whether the label is genuine. In a described implementation, the identifying indicia may be cryptographically signed.

摘要： A computer-implemented system and method for configuring and operating a white-box cipher is disclosed. In one implementation, the system employs a method for configuring pseudorandom data derived from a key to perform key-scheduling functionality associated with rounds of the cipher. Additionally, the system employs a method for generating white-box executable code, wherein the code hides the pseudorandom data by incorporating it into mathematical operations performed during execution of the rounds. Accordingly, the cipher is suited for white-box applications managing digital rights, such as decoding audio, video and other content.

摘要： This document describes tools that enable secure communication between devices that are within a user's common control. These commonly controlled devices may follow a protocol, for example, where each commits to its own public key and receives a commitment of the other's public key, publishes its own public key and receives the other's public key, and authenticates the other's public key based on the received commitment of the other's public key. If authentic, each device computes an identifier based on the other's public key and its own private key associated with its own public key. A user may interact with the devices to confirm that the identifiers are the same. If they are the same, the devices may communicate securely.

摘要： Methods and systems are described that enable protection of digital content, such as movies and the like, by making pirated copies traceable back to a unique decryption key that was utilized to decrypt the originally encrypted content. Various embodiments can intrinsically link any unauthorized copies back to a unique cryptographic key or key collection that was used when the genuine copy was reproduced.
