Samenvatting

Since DES became the rst cryptographic standard, block ciphers have been a popular construction in cryptology. Speck is a recent block cipher developed by the NSA in 2013. It belongs to the cipher family known as ARX. ARX constructions are popular because of their eciency in software. The security of the cipher is derived from using modular addition, bitwise rotation and xor. In this paper we employ linear cryptanalysis for variants of Speck with block sizes of 32, 48, 64, 96, and 128 bits. We illustrate that linear approximations with
high bias exist in variants of Speck.
