TWINE: A Lightweight Block Cipher for Multiple Platforms ⋆

Open publisher page 221 citations

Abstract

This paper presents a 64-bit lightweight block cipher TWINE supporting 80 and 128- bit keys. TWINE realizes quite small hardware implementation similar to the previous lightweight block cipher proposals, yet enables efficient software implementations on various platforms, from micro-controller to high-end CPU. This characteristic is obtained by the use of generalized Feistel structure combined with an improved block shuffle, introduced at FSE 2010. Keywords: lightweight block cipher, generalized Feistel structure, block shuffle
