简化SIMON类算法的立方测试与分析
Cube test and analysis for reduced SIMON family of block ciphers
摘要
Abstract
Focusing on the safety analysis of the SIMON lightweight block cipher,this paper proposed a method on this algo-rithm against the cube attack and cube neutral-bit detection.Using the FPGA test platform,this paper proposed a SIMON32/64 cube attack and cube neutral-bit detection algorithm by combining the basic idea of cube analysis.Simulation experiments show that when the cube variables are in the range of 6 to 24 dimensions,refering to 7-round SIMON32/64 algorithm,the al-gorithm can recover 47 bit key directly with time complexity of218.08by using cube attack.Moreover,it can recover 39 bit key on 8-round SIMON32/64 algorithm with time complexity of 225.00 by using cube attack.With regard to 10-round,1 1-round SI-MON32/64 algorithm,it can capture neutral secret key bits by using cube test.关键词
