Formal Verification of Wireless Sensor Key Exchange Protocol Using AVISPA

Abstract

For efficient deployment of sensor nodes required in many logistic applications, it's necessary to build security mechanisms for a secure wireless communication. End-to-end security plays a crucial role for the communication in these networks. This provides the confidentiality, the authentication and mostly the prevention from many attacks at high level. In this paper, we propose a lightweight key exchange protocol WSKE (Wireless Sensor Key Exchange) for IP-based wireless sensor networks. This protocol proposes techniques that allows to adapt IKEv2 (Internet Key Exchange version 2) mechanisms of IPSEC/6LoWPAN networks. In order to check these security properties, we have used a formal verification tools called AVISPA.
