SMS4 is a 32-round block cipher with 128-bit block size and 128-bit secret key. It is used in WAPI, the Chinese WLAN national standard. In this paper, we analyze the security of SMS4 against the rectangle attack. First we describe two properties of SMS4. Next, we propose the 16-round rectangle distinguisher with probability 2^-250. Finally, the rectangle attack is then carried out on 18-round SMS4...
Protein-DNA interactions play a critical role in many biological processes. However, the structural mechanisms underlying these interactions are not fully understood. DNA binding proteins can be classified into double-stranded DNA binding proteins (DSBs) and single-stranded DNA binding proteins (SSBs). Understanding the binding specificity of a DNA binding protein is helpful for the research of protein...
The interface design of software used on Home Appliances targeted at satisfying passenger's physiology and psychological needs when operating the machine to the maximum extent is a complicated synthetic topic which embracing ergonomics, visual communication design, user experience design, behavior psychology, cultural studies of the consumer, optics and Chromatics and so on. So, it is very difficult...
Graphs are widely used to model complicated data semantics in many applications in bioinformatics, chemistry, social networks, pattern recognition, etc. A recent trend is to tolerate noise arising from various sources, such as erroneous data entry, and find similarity matches. In this paper, we study the graph similarity join problem that returns pairs of graphs such that their edit distances are...
evaluating the education value of video games is a complex task. Based on the educational evaluation system for video games, we establish a corresponding automated evaluation model using the Back-propagation (BP) neural network technology. After training with the expert knowledge, the model not only has the experience of experts, but also has the computational capacity to evaluate new cases.
After characteristic analyzing of materiel development project technical capabilities, this paper defines a quantitative technical risk assessment method based on grey relevancy degree. Firstly, a set of technical capability character parameters of materiel development project and their values are retrieved by technical capability characters analyzing. Then, by task targets breaking down, every sub-task...
Guanzhong-Tianshui Economic Zone has a unique position and advantage in china. It is one of the three important economic zones in the west part in china. This article is based on the regional Competitiveness theory, use the method of factor analysis and compare guanzhong — Tianshui Economic Zone with the Western relatively developed provinces to making regional competitiveness rankings. According...
The topic of tuition fees has recently sparked heated discussions in various media. Based on China's national conditions, this article collected elevant data, such as national student average funding, training costs, household disposable income and did the quantitative analysis for tuition standards of several types of schools, then built a Multi-level fuzzy evaluation model, which regarded the tuition...
