Improved PKI Solution for Mobile Ad Hoc Networks

Due to unreliable wireless media, dynamic network topology and lack of infrastructure of mobile ad hoc network, it is very vulnerable to security threats and can be attacked more easily. Mobile ad hoc network security is becoming the problem which restricted it to be applied in actual world. The infrastructure-less nature and network dynamics of mobile ad hoc networks make the conventional PKI (Public Key Infrastructure) less suitable. In this paper, we present these challenges in detail, identify the requirements for such solutions, and propose an improved PKI solution for mobile ad hoc networks.
