Abstract
A method and apparatus for performing simultaneous data compression and encryption both compresses and encrypts data in a single step. The invention includes a novel modeling method for use in conjunction with a coder, such as an arithmetic coder. The modeling method introduces randomness into the compression process, with the result that the output stream is secure.
