Abstract

An mobile ad hoc network(MANET) is a collection of wireless computers (nodes), communicating among themselves over multi-hop paths, without the help of any infrastructure such as base stations or access points. Prior research in MANET has generally studied the routing problem in a non-adversarial setting, assuming a trusted environment. In this paper, we design and evaluate the Secure Zone Routing Protocol(T-ZRP), a secure ad hoc network routing protocol is based on the design of the hash chain. In order to support use with nodes of limited CPU processing capability, and to guard against Denial-of-Service attacks in which an attacker attempts to cause other nodes to consume excess network bandwidth or processing time, we use efficient one-way hash functions and don't use asymmetric cryptographic operations in the protocol. Proposed algorithm can safely send to data through authentication mechanism and integrity about routing establishment.

MANET(Mobile Ad-Hoc Network)은 고정된 기반이 없이 노드간의 자율적이고 독립적인 네트워크를 구성한다. 이러한 네트워크에서 경로설정은 이동성이 많은 단말들이 임시로 망을 구성하기 때문에 망 자체간 유기적으로 자주 변하며, 이로 인해 잦은 연결실패로 인한 불안전한 환경이 조성되어 경로설정을 유지하는데 많은 어려움이 있다. 이를 효과적으로 하기 위하여 ZRP(Zone Routing Protocol) 경로설정 프로토콜이 제안 되었다. 그러나 ZRP는 보안에 관한 요소를 포함하고 있지 않기 때문에, 경로설정을 할 때 DoS(Denial of Service)공격에 취약하며, 또한 키 분배에 관한 메커니즘을 가지고 있지 않기 때문에 경로가 설정되었다고 해도 실제 데이터 전송 시 제 3자에 의하여 공격당하기 쉽다. 이를 보안하기 위해서 ZRP가 경로를 설정할 때 안전하게 경로를 설정할 수 있는 S-ZRP(Secure Zone Routing Protocol) 알고리즘을 제안하였다. 제안한 알고리즘은 경로설정 패킷에 대한 무결성 보장 및 근원지 인증 메커니즘을 통해서 보다 안전하게 전송할 수 있다.
