研究领域

密码算法，密钥管理，多媒体安全与取证，

信息隐藏与数字水印技术， 票据防伪技术。

讲授课程                                                                                                                                                                                         

初等数论及其应用 (课号20240082, 本科);

教学概况                                                                                                                                                                                         

初等数论及其应用是面向计算机科学与技术专业三年级本科生的限选课，我通过讲授初等数论的知识，培养学生的思维能力和逻辑推理能力；我同时在课中强调了初等数论理论在信息安全等相关领域的应用。在研究生课程信息隐藏和数字水印技术中，我给出很多开放式题目，学生可以选择感兴趣的内容去实现和设计新的水印技术。
