  Abstract

In ad-hoc network, there is no fixed infrastructure such as base stations or mobile switching centers. The security of ad-hoc network is more vulnerable than traditional networks because of the basic characteristics of ad-Hoc network, and current routing protocols for ad-hoc networks allow many different types of attacks by malicious nodes. Malicious node can disrupt the correct functioning of a routing protocol by modifying routing information, byfalbricating false routiing information and by impersonating other nodes. We propose a rouint security mechnism based on one-time digital signature. In our proposal, we use one-time digital signatures based on one-way hash functions in order to limit or prevent attacks of malicious nodes. For the purpose of generating and keeping a large number of public key sets, we derive multiple sets of the keys from hash chains by repeated hasing of the public key elements in thefirst set. After that, each node publishes its own public keys, broadcasts routing message including one-time digital signature during route discovery and route setup. This mechanism increases the routing overhead in a highly mobile environment, but provides great security in the route discovery process adincreases the network efficiency.
