Semantic representation and interval roughness analysis of IoT CapBAC rules by Xiaoyan LIANG, Ruizhong DU

“…To break the bottleneck of interval roughness analysis, a rule semantic model IoTACS was proposed, and IoTRA algorithm was given.In IoTACS, a conceptual structure of the IoT CapBAC rule domain was proposed, the quantitative data properties of the basic concepts were given, then the semantic tree model of rule semantics was proposed, the time relations of the time ontology were extended and its quantitative logical representation was given.As the theoretical basis, it was proved that the root cause of interval inconsistency was roughness, and its logical formalization of the roughness was given.The case study shows that IoTRA can help to improve the accuracy of the authorized interval, and the IoTACS model have higher readability than the formal model.The comparison experiments with the IoTC² algorithm on the inconsistency analysis show that the response time of the IoTRA algorithm is more significantly reduced.…”

Image encryption algorithms based on chaos through dual scrambling of pixel position and bit by Xiao-heng DENG, Chun-long LIAO, Cong-xu ZHU, Zhi-gang CHEN

“…As the current popular chaos-based image encryption algorithms with the permutation–diffusion structure have security flaws of no immunity to attack.A new image encryption algorithm was proposed based on the analysis of current algorithms,which can well resist the chosen-plaintext and the chosen-ciphertext attacks.The algorithm uses Kent chaotic map to generate key streams,and produces the parameters of the chaotic system and the iteration times according to the characteristics of plaintext pixels and input key.Firstly,the positions of pixels were shuffled totally with the chaotic sequence.Secondly,the 0 and 1 bit positions of image pixels were scrambled by using another chaotic sequence generated by the input key.The experimental results show that the algorithm cannot only resist the chosen plaintext attack and chosen ciphertext attack but also achieve better cryptographic properties,such as key space,statistical analysis.…”
