Cryptanalysis of a modern rotor machine in a multicast setting

Shane Kepley, David Russo, and Rainer Steinwandt

Abstract

At FSE '93, Anderson presented a modern byte-oriented ro- tor machine that is suitable for fast software implementation. Building on a combination of chosen ciphertexts and chosen plaintexts, we show that in a setting with multiple recipients the recovery of an (equivalent) secret key can be feasible within minutes in a standard computer algebra system.
