Cryptanalysis of 6-round PRINCE using 2 Known Plaintexts

Abstract

In this paper we focus on the PRINCE block cipher reduced to 6 rounds, with two known plaintext/ciphertext pairs. We develop two attacks on 6-round PRINCE based on accelerated exhaustive search, one with negligible memory usage and one having moderate memory requirements. The time complexities for the two attacks are $2^{96.78}$ and $2^{88.85}$, respectively. The memory consumption of the second attack is less than 200MB and so is not a restricting factor in a real-world setting.
