Abstract

The boomerang aack is a new and very powerful cryptanalytic echnique. However due o he adaptive chosen plainex and cipherex nature of he aack boomerang key recovery aacks ha re- rieve key material on boh sides of he boomerang distinguisher axe haxd o moun. We also presen a method for using a boomerang distinguisher, which enables rerieving subkey bks on boh sides of he boomerang dis- inguisher. The rectangle aack evolved from he boomerang aack. In his paper we presen a new algorithm which improves he results of he rectangle aack.
