SKINNY swMATH ID: 17435 Software Authors: Beierle, Christof; Jean, Jรฉrรฉmy; Kรถlbl, Stefan; Leander, Gregor; Moradi, Amir; Peyrin, Thomas; Sasaki, Yu; Sasdrich, Pascal; Sim, Siang Meng Description: The ๐๐บ๐ธ๐ฝ๐ฝ๐ family of block ciphers and its low-latency variant ๐ผ๐ฐ๐ฝ๐๐ธ๐. We present a new tweakable block cipher family ๐๐บ๐ธ๐ฝ๐ฝ๐, whose goal is to compete with NSA recent design ๐๐ธ๐ผ๐พ๐ฝ in terms of hardware/software performances, while proving in addition much stronger security guarantees with regards to differential/linear attacks. In particular, unlike ๐๐ธ๐ผ๐พ๐ฝ, we are able to provide strong bounds for all versions, and not only in the single-key model, but also in the related-key or related-tweak model. ๐๐บ๐ธ๐ฝ๐ฝ๐ has flexible block/key/tweak sizes and can also benefit from very efficient threshold implementations for side-channel protection. Regarding performances, it outperforms all known ciphers for ASIC round-based implementations, while still reaching an extremely small area for serial implementations and a very good efficiency for software and micro-controllers implementations (๐๐บ๐ธ๐ฝ๐ฝ๐ has the smallest total number of AND/OR/XOR gates used for encryption process). Secondly, we present ๐ผ๐ฐ๐ฝ๐๐ธ๐, a dedicated variant of ๐๐บ๐ธ๐ฝ๐ฝ๐ for low-latency implementations, that constitutes a very efficient solution to the problem of designing a tweakable block cipher for memory encryption. ๐ผ๐ฐ๐ฝ๐๐ธ๐ basically reuses well understood, previously studied, known components. Yet, by putting those components together in a new fashion, we obtain a competitive cipher to ๐ฟ๐๐ธ๐ฝ๐ฒ๐ด in latency and area, while being enhanced with a tweak input.
