Biham and Kocher demonstrated that the PKZIP stream cipher was weak and presented an attack requiring thirteen bytes of plaintext. The deflate algorithm “zippers” now use to compress the plaintext before encryption makes it difficult to get known plaintext. We consider the problem of reducing the amount of known plaintext by finding other ways to filter key guesses. In most cases we can reduce the amount of known plaintext from the archived file to two or three bytes, depending on the zipper… CONTINUE READING
