Biclique Cryptanalysis of TWINE

The needs for security and privacy issues in resource constraint platforms such as RFID tags and sensor nodes give rise to design lightweight cryptographic algorithms. 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, the authors present the first single-key attacks on the both versions of the cipher. In these attacks, they use the recently developed biclique technique.
