摘要
由一名新闻记者兼机器人与机器学习每日新闻的工作人员新闻编辑-对称密码学的新研究是一份新报告的子标题。根据NewsRx记者从中华人民共和国湖北传来的消息，研究表明："本文基于Simon的周期发现量子算法，研究了分组密码的量子安全性"。新闻记者从湖北大学的研究中得到一句话：“我们探讨了周期函数和截断微分之间的关系，基本的观察是用概率为1的截断微分构造周期函数，在此基础上,我们发现了LBlock的8轮量子分辨器和SIMON-32/48/64/96/128的9/10/11/13/15轮量子分辨器,这是我们所知的最好的结果,并给出了LBlock的8轮量子分辨器和SIMON-32/48/64/96/128的9/10/11/13/15轮量子分辨器。为了探讨分组密码结构对抗基于Simon算法的量子攻击的安全界，研究了将Feistel结构、Lai-Massey结构和大多数广义Feistel结构相结合的统一结构，并估计了可构造的概率1截断微分的精确圆数。
Abstract
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.”
