Ad-hoc wireless network is an infrastructure-less network, i.e. there is no centralized coordination for the network operations. As and when a new node comes in the vicinity of the network it will spontaneously form the network. This paper presents a secure protocol for spontaneous wireless ad-hoc network which uses a hybrid symmetric/asymmetric scheme and the trust between users in order to exchange the initial data and to exchange the secret keys that will be used to encrypt the data.
