An Environment to Facilitate the Teaching of GNY-Based Security Protocol Analysis Techniques

The development of cryptographic logics to analyze security protocols has provided one technique for ensuring the correctness of security protocols. However, it is commonly acknowledged that analysis using a modal logic such as GNY tends to be inaccessible and obscure for the uninitiated. In this paper we describe a graphical tree-based specification environment which operates in conjunction with a Prolog-based GNY analyzer. This environment can be used to easily construct GNY statements using dynamically-constructed contextualized pop-up menus. We will show how this environment helps to distance students and protocol engineers from the syntactical element of GNY analysis, allowing them to focus more on the associated semantics and distil the critical issues that arise during protocol analysis. By freeing individuals to focus on an analysis, instead of hampering them with the necessary syntax, we can ensure that the fundamental concepts and advantages related to GNY analysis are kept in mind and applied as well

Facilitating the modelling and automated analysis of cryptographic protocols

Includes bibliographical references.Multi-dimensional security protocol engineering is effective for creating cryptographic protocols since it encompasses a variety of design, analysis and deployment techniques, thereby providing a higher level of confidence than individual approaches. SPEAR II, the Security Protocol Engineering and Analysis Resource n, is a protocol engineering tool built on the foundation of previous experience garnered during the SPEAR I project in 1997. The goal of the SPEAR II tool is to facilitate cryptographic protocol engineering and aid users in distilling the critical issues during an engineering session by presenting them with an appropriate level of detail and guiding them as much as possible. The SPEAR II tool currently consists of four components that have been created as part of this dissertation and integrated into one consistent and unified graphical interface: a protocol specification environment (GYPSIE), a GNY statement construction interface (Visual GNY), a Prolog-based GNY analysis engine (GYNGER) and a message rounds calculator
