A Tangible-Tool-Based Lesson Plan on Cipher Key Exchange Protocol for Early-Stage Learners |

|---|---|---|
In today's technology-dominated world, in order to better equip the next generation of youth with technological skills suitable for future jobs, pre-tertiary and early tertiary curricula are being significantly revamped all over the world. In line with this drive, as a STEM discipline, Computer Science (CS) is also being widely incorporated in recent curricular initiatives. Information security is one of core areas of CS. Security concepts often entail esoteric mathematical ideas which are difficult to explain to early-stage learners, which necessitates contriving new and engaging ways of teaching. This paper deals with teaching of one such security concept - namely, Diffie-Hellman key exchange protocol - to early-stage learners. Traditionally, a color-mixing analogy has been used for introducing the concept of Diffie-Hellman key exchange protocol. Although this approach elegantly exemplifies the discrete logarithm problem on which the protocol is based, depending on how the lesson is executed, it can be passive, or require a new supply of liquid colors for each lesson. Therefore, we have developed a digital version of the color-mixing approach - while retaining active student participation and tangibility - by using color sensors and Raspberry Pi. We also propose a mission-based lesson plan based on the tangible tool for enabling young pupils to comprehend difficult concepts. Our pilot study using the tangible-tool-based lesson plan showed promising results as the participants found the lesson engaging and enriching. We also believe, as an unplugged approach, our low-cost and reusable tangible tool can help ensure universal access to education in developing countries. |
