Understanding Phase Shifting Equivalent Keys and Exhaustive Search
Côme Berbain, Aline Gouget, and Hervé Sibert
Abstract
Recent articles~\cite{kucuk,ckp08,isobe,cryptoeprint:2008:128} introduce the concept of phase shifting equivalent keys in stream ciphers, and exploit this concept in order to mount attacks on some specific ciphers. The idea behind phase shifting equivalent keys is that, for many ciphers, each internal state can be considered as the result of an injection of a key and initialization vector. This enables speeding up the standard exhaustive search algorithm among the
