| Abstract: | 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 PRINCEcore.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 PRINCEcore.Using 2-round differential-linear distinguisher, 4-round PRINCEcorecan be broken with 26chosen plaintext and 214.58encryption.For 6-round and 7-round PRINCEcore, the data complexity is 212.84and 229.02respectively, and the time complexity is 225.58and 241.53. |
