SECURITY IN WIRELESS AD HOC NETWORKS ECE 646 Prof Dr. Kris Gaj Amarnath Reddy Peddareddy Wari Karthikeyan Paramasivam Sundhar LakshminarasimhanAbstract An ad hoc network is a collection of wireless nodes that dynamically form a temporary network and operates without the use of existing network infrastructure. In the near future, many personal electronic devices will be able to communicate with each other over a short-range wireless channel. We investigate the principal security issues for such an environment. The traditional way of protecting networks with firewalls and encryption software is no longer sufficient and effective. We need to search for new architecture and mechanisms to protect the wireless networks and mobile computing application. List of alternative protocols/algorithms/implementations/laws you are planning to compare: 1. Security in various Ad Hoc Protocols. • Dynamic Destination Multicast protocol (DDM) • Optimized Link State Routing protocol (OSLR) • On-Demand Multicast Routing Protocol (ODMRP) • Ad Hoc On-Demand Distance-Vector routing protocol (AODV) • Topology Broadcast based on Reverse-Path Forwarding (TBRPF) 2. Techniques to key agreement • Password based Authenticated Key Exchange • Password authenticated Deffie-Hellman Key Exchange 3. Basic properties of trust and their role for security: • Distributed trust model • Password-based Key Agreement • Resurrecting Duckling Security Policy • Distributed Public-Key Management 4. Intrusion Detection techniques in Ad-hoc networks Description of problems/hypothesis we are planning to investigate: 1. Attacks and possible solutions to secure routing • Internal attacks • External attacks 2. Security requirements of ad-hoc networks • Availability. • Confidentiality • Integrity • Non-repudiation 3. Security issues in routing protocols for Ad-hoc networks 4. Security issues in Key Management 5. Issues in designing Intrusion Detection for Ad-hoc networksA list of questions • Why Ad-hoc? • What are the different types of attacks against wireless ad-hoc networks • How does each protocol handle security services? • What are the future applications of Wireless Ad Hoc networks? • What are various security models proposed for ad-hoc network? • What are basic security requirement for add-hoc network? • What is the overhead involved in routing protocols used in Ad Hoc networks • What are the current routing protocols used in Ad Hoc networks • How is a trusted node formed? • How to determine bad node? • How is Key management established? • What is intrusion detection and how is it established? Procedure for verifying the results of investigation The results of our investigation will be based on extensive data collection from various sources that include technical documents, white papers, and periodicals. A thorough web search is in progress. Format and Tentative table of contents: 1. Introduction 1.1 Security Issues in Ad-hoc networks. 1.2 Secure Routing 1.3 Key Management 1.4 Intrusion Detection 2.
