Impossible differential cryptanalysis is an analysis method by constructing impossible differential path, eliminating the keys satisfying this path, and finally recovering the secret keys. This paper has utilized a new property of Mix Columns Transformation, constructed a new 4-round impossible differential path, added 1-round and 3-round possible differential path before and behind this path respectively,...
Internet of Things (IOF) is the outcome of the combination of sensor technology and Internet development. It is an important part of future Internet. Due to the complexity and unpredictability of IOF, data management of IOF faces great challenges. This paper first briefly introduces the concept of IOF. Based on the characteristics of IOF such as mass scale, data polymorphism, rich semantic, and real-time...

In the aviation industry, each aircraft is equipped with flight recorders. The scheme of this paper is that the same idea can be introduced in each copy of software. Once a software black-box mechanism is incorporated into a copy of a software product, the data used for software maintenance can be collected in real time. The software black-box information can be fed back to the producer at any time...
