A Dynamic Key Agreement Mechanism for Mission Critical Mobile Ad Hoc Networking
Mobile ad hoc networks are expected to play an important role in demanding communications such as military and emergency response. In Mobile ad hoc networking each node relies on adjacent nodes in order to achieve and maintain connectivity and functionality. While offering many advantages, such as flexibility, easy of deployment and low cost, mobile ad hoc networking faces important security threats that could be proven vital in future telecommunication applications. This paper introduces a key dynamic agreement method based on a weak to strong authentication mechanism associated with a multiparty contributory key establishment method. It is designed for dynamic changing topologies, it employs elliptic curve cryptography to best serve thin clients with energy constrains, and reduces significantly key re-establishment due to network formation changes.
