Biclique Cryptanalysis of TWINE
Abstract
TWINE is a lightweight block cipher proposed at ECRYPT Workshop on Lightweight Cryptography 2011, Belgium. The cipher consists of 36 rounds and has two versions TWINE-80 and TWINE-128 supporting key lengths of 80 and 128 bits, respectively. The block length of the two versions is 64-bit. In this paper, we present the first single-key attacks on the both versions of the cipher. In these attacks, we use the recently developed biclique technique. The complexities of the attacks on TWINE-80 and TWINE-128 are $2^{79.10}$ and $2^{126.82}$ respectively and the data requirement for the two attacks is $2^{60}$.
