By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News – New research on symmetric cryptology is the subje ct of a new report. According to news originating from Hubei, People’s Republic of China, by NewsRx correspondents, research stated, “In this paper, we study th e quantum security of block ciphers based on Simon’s period-finding quantum algo rithm.” The news reporters obtained a quote from the research from Hubei University: “We explored the relations between periodic functions and truncated differentials. The basic observation is that truncated differentials with a probability of 1 ca n be used to construct periodic functions, and two such constructions are presen ted with the help of a new notion called difference-annihilation matrix. This te chnique releases us from the tedious manual work of verifying the period of func tions. Based on these new constructions, we find an 8-round quantum distinguishe r for LBlock and a 9/10/11/13/15-round quantum distinguisher for SIMON-32/48/64/ 96/128 which are the best results as far as we know. Besides, to explore the sec urity bounds of block cipher structures against Simon’s algorithm based quantum attacks, the unified structure, which unifies the Feistel, Lai-Massey, and most generalized Feistel structures, is studied. We estimate the exact round number o f probability 1 truncated differentials that one can construct.”
