METHOD, SYSTEM AND DEVICE FOR GENERATING A PSEUDORANDOM DATA SEQUENCE

摘要

The invention concerns a device and a method for generating a pseudorandom data sequence (1) from an initial dataflow (3) characterized in that it includes the following steps: defining a set of code words forming a complete prefix code (5); defining a set of output words (7); defining a desynchronizing function (f) associating with any code word of said complete prefix code (5) an output word of said set of output words (7); breaking down the initial data flow (3) into a coded sequence of words (11) in conformity with said complete prefix code (5); associating the words of said coded sequence of words (11) with the corresponding output words in conformity with said desynchronizing function (f) to form said pseudorandom data sequence (1).
