| Summary: | PRINCE is a low-latency lightweight block cipher, which is widely used in a lot of resource constrained devices.It is based on the FX construction and the core component is PRINCE<sub>core</sub>.Differential-linear cryptanalysis is a classical cryptographic technique, which combines differential cryptanalysis and linear cryptanalysis together.Short differential characteristics and linear characteristics with high-probability were concatenated to break the cipher.Differential-linear cryptanalysis were applied to attack PRINCE<sub>core</sub>.Using 2-round differential-linear distinguisher, 4-round PRINCE<sub>core</sub>can be broken with 2<sup>6</sup>chosen plaintext and 2<sup>14.58</sup>encryption.For 6-round and 7-round PRINCE<sub>core</sub>, the data complexity is 2<sup>12.84</sup>and 2<sup>29.02</sup>respectively, and the time complexity is 2<sup>25.58</sup>and 2<sup>41.53</sup>. |
