Related-mode attacks on block cipher modes of operation

Abstract

In this paper, we present a generalization of the notion of the recently proposed related-cipher attacks. In particular, we show that when the cryptanalyst has access to an oracle under one mode, then almost all other related-cipher modes can be attacked with ease. Typically only one chosen plaintext/ciphertext query is required, while computational complexity is negligible. © Springer-Verlag Berlin Heidelberg 2005.
