摘要：Because of lack of infrastructure and Central Authority(CA), secure communication isa challenging job in MANETs. A lightweight security solution is needed in MANET to balance itsnodes resource tightness and mobility feature. The role of CA should be decentralized in MANETbecause the network is managed by the nodes themselves without any xed infrastructure and cen-tralized authority. In this paper, we created a distributed PUblic Key Infrastructure (PKI) usingShamir secret sharing mechanism which allows the nodes of the MANET to have a share of its pri-vate key. The traditional PKI protocols require centralized authority and heavy computing power tomanage public and private keys, thus making them not suitable for MANETs. To establish a securecommunication for the MANET nodes, we proposed a lightweight crypto protocol which requireslimited resources, making it suitable for MANETs.
