Abstract.
Because of lack of infrastructure and Central Authority(CA), secure communication is
a challenging job in MANETs. A lightweight security solution is needed in MANET to balance its
nodes resource tightness and mobility feature. The role of CA should be decentralized in MANET
because the network is managed by the nodes themselves without any fixed infrastructure and centralized
authority. In this paper, we created a distributed PUblic Key Infrastructure (PKI) using
Shamir secret sharing mechanism which allows the nodes of the MANET to have a share of its private
key. The traditional PKI protocols require centralized authority and heavy computing power to
manage public and private keys, thus making them not suitable for MANETs. To establish a secure
communication for the MANET nodes, we proposed a lightweight crypto protocol which requires
limited resources, making it suitable for MANETs.
