摘要： Methods, devices, and systems of protecting a secret are provided. Access to the secret is designed to be restricted to a code with a specific signature, or fingerprint. The signature of that code is used in the encryption of the secret, and other codes are prevented from using this signature to decrypt the secret. This restricted access to the secret prevents the secret from being easily compromised, for example, by preventing a change in the code.

摘要： A secure virtual machine system, method, and computer program product implemented on a processor are provided for processing a third party's content for output. At least one processor is provided. Additionally, at least one secure virtual machine implemented on the processor is provided for interpreting a second party's program that processes and outputs a third party's content. The virtual machine system abstracts the underlying processor hardware allowing implementation variations across products to execute the same program identically. Furthermore, the scope of the programmable operations, the types of input & output variables, and execution of programs within the processor, is deliberately constrained within the virtual machine environment, in order to mitigate potential security leaks by programs, and to ensure confidentiality of second party's secrets, and third party's content as managed by the second party's program.

摘要： A system, method, and computer program product are provided for buffering an audio video (AV) stream, audio/video header information, and an audio/video elementary stream for hardware audio/video digital rights management (DRM) processing. In operation, an AV stream encrypted under a shared symmetric key in an M2TS format is buffered, where the AV stream includes content including at least one of audio or video and all content data associated with the AV stream is removed at picture level and below, with the exception of content headers associated with the content data. Additionally, content header information encrypted under the shared symmetric key is buffered, the content header information indicating locations of the content headers associated with the content data. Further, a content elementary stream encrypted under a hardware secret key is buffered for consumption of a hardware bit stream decoding engine.
