以RSA体制为核心的《电子商务安全》课程案例教学设计

Case Teaching Design of Electronic Commerce Security Course with the RSA Cryptosystem as the Core Content

《电子商务安全》是一门理论性较强的信息安全类课程。由于与《密码学》课程存在教学内容重叠的现象,使得教师往往不易把握该课程的教学内容深度。为此,提出"以RSA体制为核心,通过反复引入该体制的应用案例来帮助学生加深对《电子商务安全》课程内容的理解"的观点,并且结合RSA-OAEP方案和基于RSA-OAEP的两方密钥交换协议设计具体的教学案例。通过在教学设计中引入案例教学法,最终取得预期的效果。

Electronic Commerce Security is a highly theoretical course of information security. Because of its overlapping with the course of ＂Cryptography＂ in teaching content, teachers are not easy to grasp the teaching depth in classes of Electronic Commerce Security. Puts forward that the RSA cryptosystem should be taken as the core content, and through repeated explanations and applications of this system, students are promoted to deepen their understanding of the whole content of e-commerce security. At the same time, proposes a specific teaching case, which is based on the RSA-OAEP encryption scheme and a two party key exchange protocol based on RSA-OAEP. It should be mentioned that the teaching design has achieved good effects by introducing the case teaching method.
