Abstract: The systematic construction of ideological and political education into the cryptographic security protocol course involves designing course content in a structured manner that incorporates ideological and political education alongside the technical curriculum. The goal is to cultivate students with ethical values and social responsibility while equipping them with Marxist methodologies to guide their academic practices in cryptographic security protocols. First, by analyzing the characteristics of the cryptographic security protocol course, ideological and political elements are integrated into each chapter in the form of tiered indicators. Second, specific content and teaching methods for incorporating ideological and political elements into course chapters are designed, along with illustrative case studies for reference. Finally, the significance of the systematic integration of ideological and political education into the cryptographic security protocol course is summarized. Additionally, the systematic approach proposed in this study provides valuable insights and references for the systematic incorporation of ideological and political education into other specialized courses.
