An efficient key agreement scheme for infrastructure less wireless network (ILWN)

For the last decade or so wireless and mobile communication and its application has been enjoying tremendous attention because of their unique features. More recently, an increasing emphasis has been on the potential of infrastructure less wireless mobile networks that are easy, fast and in-expensive to set up, with the view that such technologies will enable numerous new applications in a wide range of areas. However, security in ILWN is still its primary stage as very little attention has been devoted so far to this topic by the research community. We identify the initial exchange of authentication and key credentials, referred to as pre-authentication, as well as authentication and key exchange as primary security goals. In particular, the problem of authentication has been widely neglected in existing security solutions, even though it is a necessary pre-requisite for other security goals. The Elliptic curve crypto system (ECC) provides more security in less key length which makes is energy efficient. Through a thorough study and implementation we show the scheme provide better security to infrastructure less wireless networks.
