Abstract:
Saturnin is a suite of lightweight symmetric algorithms which is proposed in ToSC2020 and also is a second-round NIST Lightweight competition candidate. Its aim is to provide security both in classical and post-quantum setting. In this paper, we provide a security analysis of Saturnin block cipher against integral distinguisher using bit-based division property and propose a 9-round integral characteristic, which is the first integral cryptanalysis results externally published on Saturnin. We also provide an evaluation of the tightness of the data complexity bounds for integral distinguishers given by the designers for a different number of rounds of Saturnin.
