Title:
Related-Key Differential Attack on Round Reduced RECTANGLE-80
Authors: Jinyong Shan, Lei Hu, Ling Song, Siwei Sun, Xiaoshuang Ma
Abstract:RECTANGLE is a newly proposed lightweight block cipher which allows fast implementations for multiple platforms by using bit-slice techniques. It is an iterative 25-round SPN block cipher with a 64-bit block size and a 80-bit or 128-bit key size. Until now, the results on analyzing the cipher are not too much, which includes an attack on the 18-round reduced version proposed by the designers themselves. In this paper, we find all 15-round differential characteristics with 26–30 active S-boxes for given input, output and round subkey differences, which have a total probability 2^{-60.5}. Based on these differential characteristics, we extend the corresponding distinguisher to 2 rounds backward and forward respectively, and propose an attack on the 19-round reduced RECTANGLE-80 with data complexity of 2^{62} plaintexts, time complexity of about 2^{67.42} encryptions and memory complexity of 2^{72}. TThese data and time complexities are much lower than that of the designers for the 18-round reduced RECTANGLE-80.
