Abstract—We have designed and developed a 3D digital Lego system as an education tool for teaching security protocols effectively
in Information Assurance courses (Lego is a trademark of the LEGO Group. Here, we use it only to represent the pieces of a
construction set.). Our approach applies the pedagogical methods learned from toy construction sets by treating security primitives as
Lego pieces and protocols as construction results. Simulating the Lego toys, the digital Legos use matching shapes to help students
understand the relationships among security primitives and protocols. Specifically, we present a flexible Lego generation method that
can use various intuitive shapes to represent abstract and complex security protocols. Our design allows easy generation of new Lego
sets and creation of different course materials. The integrated system also provides 3D interaction methods that simulate the real
Lego building experience. For selected security courses, we have designed sample demonstrations and experiments for a set of
important protocols. The initial evaluation results show encouraging feedback from students on using digital Legos in introductory
security courses.

1 INTRODUCTION
INFORMATION assurance education for both college students
and the general public has been well recognized by many
universities as an important topic since the early nineties.
For example, Pothamsetty has investigated 25 security
courses offered by multiple universities that are designated
as NSA Centers of Academic Excellence, and found that
most of them adopted a curriculum structure of introductory-
advanced information assurance courses [1]. Our
experiences in teaching introductory and advanced security
courses have led us to realize that there exists a gap
between the teaching of security primitives and protocols,
which may severely impact the learning outcomes of
information assurance education. It has been shown that a
group of secure primitives may finally compose vulnerable
protocols if they are inappropriately organized. Therefore,
special efforts must be made in the course plan to cultivate
the capability of students to select suitable primitives and
organize them appropriately. We believe that an interactive
education environment for demonstration and exercises can
help bridge this teaching gap.
The objective of this project is to develop an innovative
