    Effects of Limited Computational Precision on the Discrete Chaotic Sequences and the Design of Related Solutions.Chunlei Fan & Qun Ding - 2019 - Complexity 2019:1-10.
    In this paper, we analyzed the periodicity of discrete Logistic and Tent sequences with different computational precision in detail. Further, we found that the process of iterations of the Logistic and Tent mapping is composed of transient and periodic stages. Surprisingly, for the different initial iterative values, we first discovered that all periodic stages have the same periodic limit cycles. This phenomenon has seriously affected the security of chaotic cipher. To solve this problem, we designed a novel discrete chaotic sequence (...)

    A Color Image Encryption Scheme Based on a Novel 3D Chaotic Mapping.Chunyuan Liu & Qun Ding - 2020 - Complexity 2020:1-20.
    Low-dimensional chaotic mappings are simple functions that have low computation cost and are easy to realize, but applying them in a cryptographic algorithm will lead to security vulnerabilities. To overcome this shortcoming, this paper proposes the coupled chaotic system, which coupled the piecewise and Henon mapping. Simulation results indicate that the novel mapping has better complexity and initial sensitivity and larger key space compared with the original mapping. Then, a new color image encryption algorithm is proposed based on the new (...)

    Agency and social capital in Chinese international doctoral students’ conversion to Christianity.Qun Ding & Nesta Devine - 2017 - Educational Philosophy and Theory 49 (12):1161-1172.
    Chinese international students constitute the largest proportion of overseas students in several English-speaking countries such as the UK and New Zealand. Little research has been done concerning those undertaking doctoral study. This qualitative study explores how Chinese overseas doctoral students become involved in church communities and how some of them convert to Christianity in New Zealand. In-depth interviews were conducted with nine Chinese doctoral students from different social backgrounds. Five of these reported varying degrees of interest in and commitment to (...)
