METHOD FOR RECORDING OF ENCRYPTED DIGITAL DATA, RECORDING DEVICE AND DECODER FOR THE APPLICATION IN THE ADVISED METHOD, FURTHER PORTABLE SECURITY MODULE FOR THE APPLICATION IN THE RECORDING DEVICE AND DECODER

摘要

A method for recording transmitted digital data, wherein the transmitted digital information is encoded by a coding key and stored on a recording medium by a recording device, and the equivalent of the encoding key is encoded with a recording forward key and stored on the media medium by the encoded information set. A recording device for implementing the proposed method comprising a key coding security module encoding a transmitted digital information for storing on a recording medium, wherein the security module encodes the encoding key for recording on a recording medium with a recording transmission key. A decoder for the application in process, which includes a copy forward security security module for the recording forward key. A portable security module for use in a recording device, comprising a recording encoding key encoding a digital information transmitted from its subsequent recording destination, and a recording transmission key encoding a recording encoding key following a recording destination. A portable security module for use in the decoder, comprising at least a single-shot transmission key copy. HE
