Practical Attacks on the Round-reduced PRINCE

Pawel Morawiecki

Abstract: The PRINCE cipher is the result of a cooperation between the Technical University of Denmark (DTU), NXP Semiconductors and the Ruhr University Bochum. The cipher was designed to reach an extremely low-latency encryption and instant response time. PRINCE has already gained a lot of attention from the academic community, however, most of the attacks are theoretical, usually with very high time or data complexity. Our work helps to fill the gap in more practically oriented attacks, with more realistic scenarios and complexities. We present new attacks, up to 7 rounds, relying on integral and higher-order differential cryptanalysis.

Category / Keywords: secret-key cryptography / PRINCE, lightweight cryptography, integral cryptanalysis, higher-order differential
