| 中文摘要 | PRINCE is a low-latency block cipher presented at ASIACRYPT 2012. The cipher was designed with a property called α-reflection which reduces the definition of the decryption with a given key to an encryption with a different but related key determined by . In the design document, it was shown that PRINCE is secure against known attacks independently of the value of , and the design criteria for remained open. In this paper, we introduce new generic distinguishers on PRINCE-like ciphers. First, we show that, by folding the cipher in the middle, the number of rounds can be halved due to the α-reflection property. Furthermore, we investigate many classes of α and find the best differential characteristic for the folded cipher. For such α there exist an efficient key-recovery attack on the full 12-round cipher with the data complexity of 257.98 known plaintexts and time complexity of 272.39 encryptions. With the original value of we can attack a reduced six-round version of PRINCE. As a result of the new cryptanalysis method presented in this paper, new design criteria concerning the selection of the value of for PRINCE-like ciphers are obtained. © 2014 Springer-Verlag. |
