PPT：基于实训平台的数据安全应用类教学模式探索——以《现代密码学》课程为例
PPT: A Practical Platform-Based Teaching for Data Security Courses—Taking Modern Cryptography as an Example

随着《中华人民共和国密码法》的颁布实施，数据安全的重要性已上升到了国家安全的层面。然而传统的数据安全类课程普遍以理论知识点讲授为主，缺少在实际信息系统中对相关知识点的串联讲解。整个课程体系也缺少对实际应用的支撑，导致学生无法体会学习相关理论知识的原因、意义和目的，造成学生学习的兴趣较低。为此，本文提出一种基于实训平台的教学(Practical Platform-based Teaching, PPT)模式，并以《现代密码学课程》为例，介绍PPT模式如何以实训平台为基础、以面向实际业务场景自顶向下的课程大纲为核心解决上述问题。除数据安全类课程外，PPT教学模式还可支撑其他面向应用的计算机类专业课程。
Since the enforcement of the Cryptographic Law of the People’s Republic of China, data security has emerged as a critical aspect of national security. However, traditional data security courses primarily focus on theoretical concepts, often lacking practical scenarios that integrate these concepts effectively. Additionally, practical applications of the theory are often missing from the curriculum. As a result, students struggle to grasp the rationale, significance, and purpose of learning these theoretical concepts, leading to a lack of interest in the courses. To tackle these challenges, we propose the adoption of a Practical Platform-Based Teaching (PPT) approach. Taking Modern Cryptography as an example, we demonstrate how PPT addresses the aforementioned issues by incorporating a practical platform and following a top-down curriculum methodology. Furthermore, it is worth not-ing that PPT is not limited to data security courses alone. It has the potential to support various application-oriented major courses within the field of computer science.
