Cryptanalysis of Reduced round SKINNY Block Cipher
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and related-tweake impossible differential characteristics for different versions of SKINNY. We utilize meet-in-the-middle approach to construct 9-round and 10-round zero-correlation linear distinguisher. We also obtain 12-r...
متن کاملCryptanalysis of Reduced-Round Midori64 Block Cipher
Midori is a hardware-oriented lightweight block cipher designed by Banik et al. in ASIACRYPT 2015. It has two versions according to the state sizes, i.e. Midori64 and Midori128. In this paper, we explore the security of Midori64 against truncated differential and related-key differential attacks. By studying the compact representation of Midori64, we get the branching distribution properties of...
متن کاملCryptanalysis of Reduced-Round MIBS Block Cipher
This paper presents the first independent and systematic linear, differential and impossible-differential (ID) cryptanalyses of MIBS, a lightweight block cipher aimed at constrained devices such as RFID tags and sensor networks. Our contributions include linear attacks on up to 18-round MIBS, and the first ciphertext-only attacks on 13-round MIBS. Our differential analysis reaches 14 rounds, an...
متن کاملImpossible Differential Cryptanalysis of Reduced-Round Midori64 Block Cipher (Extended Version)
Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differ- ential cryptanalysis, we analyze security of a family of lightweight block ciphers, named Midori, that are designed considering low energy consumption. Midori state size can be either 64 bits for Midori64 or 128 bits for Midori128; however, both vers...
متن کاملImpossible Differential Cryptanalysis of Reduced-Round SKINNY
SKINNY is a new lightweight tweakable block cipher family proposed by Beierle et al. at CRYPTO 2016. SKINNY has 6 main variants where SKINNY-n-t is a block cipher that operates on n-bit blocks using t-bit tweakey (key and tweak) where n = 64 or 128 and t = n, 2n, or 3n. In this paper, we present impossible differential attacks against reduced-round versions of all the 6 members of the SKINNY fa...
