Greenpass, developed by Nick Goffee, Sung Hoon Kim, Meiyuan Zhao and John Marchesini under the supervision of Sean Smith and Punch Taylor, is a wireless security solution that implements SPKI/SDSI delegation on top of X.509 keypairs within the EAP-TLS authentication protocol. This system aims to model the decentralized way that authorization flows in real-world enterprise settings and provide a seamless solution that allows for easy access to all resources in the network by both registered users and authorized guests. These goals are achieved through the deployment of a delegation tool, which allows an active entity associated to the organization's network to grant authorization to another entity previously unauthorized to use the network. This paper describes the testing process of the first prototype for this system. It examines trust and usability issues of the Greenpass Wireless Security System and determines the accuracy of the system's implementation in relation to its objectives. It then addresses the planning and execution of a small-scale demo for this prototype based on the examined issues and makes projections for further tests on a larger scale.
