With an ever-evolving battlefield in cyberspace, it is essential to stay abreast of current and developing security protocols that will maintain a state of authenticity, confidentiality, and integrity between communicating entities in information-contested environments. The Department of Defense is interested in transitioning its mission objective goals to establishing and maintaining a reliable security posture between communicating command-and-control platforms. However, the current security protocol visualizations need to cater more to military users and decision-makers to help decide which security protocols would best accommodate various operational environments. This research designed and developed a two-dimensional protocol visualization tool (ProVis) that simulates various security protocol interactions in non-contested and contested operational study environments that assist with understanding how security protocols work in the context of military-related usage. A user study was conducted to examine users’ understanding, accuracy, and overall benefit of ProVis concerning the visualization of the Transport Layer Security, Message Layer Security, and Pre-Shared Key protocols. The findings are highly satisfactory: the user subjects were able to easily interface with ProVis and complete the tasks given. The user subjects found ProVis to be a helpful tool in understanding security protocols quickly. This research provides an alternative to current visualization tools.
