Security Based on User Trust in Spontaneous Wireless Ad Hoc Network Creation

Abstract — Security in wireless ad hoc networks is hard to achieve due to the absence of centralized management point. Security in wireless ad hoc networks usually relies on the use of predistribution key mechanisms. Spontaneous network is a special case of ad-hoc network, they are independent of central server having no interference of an extern user. In this paper, spontaneous wireless ad hoc network uses a hybrid symmetric/asymmetric scheme. Trust is based on first visual contact. A user is able to join the network, if user knows someone that belongs to network.A user can able to leave or join the network at any time.It is complete self-configured protocol, which is able to create a secure network and share services without any infrastructure. A user can create its own resources or they can request from its neighbor user, because it allows resource sharing and offer new services in a secure environment. Design of a protocol permits the management and creation of a spontaneous wireless ad hoc network
