Simulation Results Using AVISPA Tool Sample Clauses

Simulation Results Using AVISPA Tool. ‌ AVISPA is one of the publicly accepted Internet schemes verification techniques among many developed semi-automated formal security analysis tools and several schemes [30,31] have been analyzed using it. It is a push-button tool for error detection based on the Dolev and Yao model [32] and provides a modular role-based expressive formal language called the HLPSL (High level protocol specification language) for targeting the design of the schemes. The HLPSL presentation of the protocol is translated into the lower level description language called IF (Intermediate Format) by the translator called HLPSL2IF, which is the entrance of architecture of AVISPA. IF presentation of the scheme is used as the start point to the four various back-ends: OFMC (On the-fly Model-Checker), CL-AtSe (CL-based Attack Searcher), SATMC (SAT-based Model-Checker) and TA4SP (Tree-Automata based Protocol Analyzer). These back-ends are utilized to analyze different security properties such as secrecy of the shared session key, authentication, the privacy of user and robustness against replay attacks. The OF (output format) is generated by using one of the four back-ends which measures whether the security scheme is SAFE or UNSAFE and under what conditions it has been obtained. In order to evaluate the security of the proposed AKA scheme by the AVISPA tools, we have implemented the specifications for the user Ui (Appendix A, Figure A1), the sensor node SNj (Appendix A, Figure A2), the gate-way node GWN (Appendix A, Figure A3), the session (Appendix A, Figure A4), goal and the environment (Appendix A, Figure A5) in HLPSL. The desired goals, mutual authentication between Ui and GWN by checking Ei and Ki, between GWN and SNj by checking Gi
