Non-Repudiation in Pure Mobile Ad Hoc Network

چکیده
Within the last decade, the use of wireless technologies has become more prevalent. Wireless networks have flexible architectures with data transferred via radio waves and can be divided into two categories; infrastructure-based wireless networks and mobile ad hoc network. The mobile ad hoc network (MANET) is an autonomous system which can be dynamically built without preexisting infrastructure or a trusted third party (TTP). Due to these infrastructure-less and self-organized characteristics, MANET encounters different problems from infrastructure-based wired network, such as key management, power shortage, and security issues. This paper will further divide MANETs into pure ad hoc networks which do not contain a TTP and organized ad hoc networks which contain an offline TTP, and then focus on the security issues especially the non-repudiation issue between two mobile nodes which communicate in pure ad hoc networks.

Verifiable Agreement: Limits of Non-repudiation in Mobile Peer-to-Peer Ad Hoc Networks
We introduce verifiable agreement as a fundamental service for securing mobile peer-to-peer ad hoc networks, and investigate its solvability. Verifiability of a protocol result means that the participants can prove that the protocol reached a particular result to any third party (the verifier) which was not present in the network at the time of the protocol execution.
متن کاملRouting Protocol Based Shared and Session Key Exchange Protocol for Wireless Mobile Ad-hoc Network
Mobile Ad-hoc Network (MANET) is a transitory and infrastructureless network supported by no fixed trusted infrastructure. To achieve security goals like: authentication, integrity, non-repudiation, privacy, a secret key (or session key) is necessary to be shared between the sender and receiver. Because of the nature of MANET, it is unrealistic in many circumstances to implement Certification A...
متن کاملPublic-Key Management System using Hamming Distance for Mobile Ad Hoc Network
Mobile ad-hoc networks have various implementation constraints such as infrastructure-free, non-trusted authority, node mobility, and the limited power and small memory of mobile device. And just like wired networks, various security issues such as authentication, confidentiality, integrity, non-repudiation, access control, availability, and so on, have been arisen in the mobile ad-hoc networks...
متن کاملSecurity Issues Pertaining to Ad-Hoc Networks - A Survey
A mobile ad-hoc network (MANET) is a self-configuring network of mobile routers (and associated hosts) connected by wireless links—the union of which form an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily; thus, the network's wireless topology may change rapidly and unpredictably. MANETs are usually set up in situations of emergency for temporary o...
متن کاملLayered security design for mobile ad hoc networks
When security of a given network architecture is not properly designed from the beginning, it is difficult to preserve confidentiality, authenticity, integrity and nonrepudiation in practical networks. Unlike traditional mobile wireless networks, ad hoc networks rely on individual nodes to keep all the necessary interconnections alive. In this article we investigate the principal security issue...
