针对现代密码分析学教学内容覆盖面广、支系庞杂等问题，提出现代密码分析学课程的“矩阵式”教学方法，将分析对象列为纵向维度，将密码分析方法列为横向维度，以“矩阵式”结构串联教学内容。教师根据学生基础和课时安排选取矩阵元素纳入课堂讲解，保证每种目标密码算法均被覆盖，每种分析方法均有应用。该教学方法使得学生清晰掌握课程脉络，对密码分析方向兴趣增强，在密码学相关科创竞赛中表现优异。

Addressing the issues of broad coverage and complex subfields in modern cryptanalysis teaching content, this paper proposes a “matrix-based” teaching method for modern cryptanalysis courses. The cryptanalysis targets are listed as the vertical dimension, and the cryptanalysis methods are listed as the horizontal dimension, with the teaching content interconnected through a matrix-based structure. Instructors select matrix elements based on students' foundational knowledge and class schedules to incorporate into classroom instruction, ensuring that every target cryptographic algorithm is covered and every cryptanalysis method is applied. This teaching method enables students to clearly grasp the course structure, enhances their interest in cryptanalysis, and leads to outstanding performance in cryptography-related innovation and entrepreneurship competitions.
