PhD Theses

Own PhD Thesis

Shujun Li, "Analyses and New Designs of Digital Chaotic Ciphers (数字化混沌密码的分析与设计)," PhD thesis, School of Electronic and Information Engineering, Xi'an Jiaotong University, supervised by Prof. Yuanlong Cai and Prof. Xuanqin Mou, submitted in April 2003, defense passed on 13 June 2003, approved on 30 June 2003 (last modified on 16 November 2007, to correct minor errors and to update references) (2004 Outstanding PhD Thesis Award, Education Department of Shaanxi Provincial Government (陕西省教育厅); 2004 Outstanding PhD Thesis Award, Xi'an Jiaotong University (西安交通大学))
Note: The survey on chaotic cryptography included in Chapter 2 of the thesis has been outdated to some extent, see the following two talks that Shujun LI delivered in 2005 for more information: Digital Chaotic Ciphers (, 1.03MB), Analog Chaos-Based Secure Communications (, 4.34MB). For an extended version of Chapter 3, see the paper "On the Dynamical Degradation of Digital Piecewise Linear Chaotic Maps" () published in International Journal of Bifurcation and Chaos in 2005.
