The attack consists of a precomputation and an elimination phase. The attack reduces the number of required plaintexts significantly for 4 and 4.5 rounds, and, to the best of our knowledge, it is the first attack on the 5-round IDEA. © Springer-Verlag Berlin Heidelberg 2004.EnglishA new meet-in-the-middle attack on the IDEA block cipherArticle10.1007/978-3-540-24654-1_9
