Secure Service Discovery Protocol for Ad Hoc Networks Using Hash Function

摘要

Ad-hoc networks, mobile devices communicate via wireless links without the aid of any fixed networking infrastructure. These devices must be able to discover services dynamically and share them safely, taking into account ad-hoc networks requirements such as limited processing and communication power, decentralized management, and dynamic network topology, among others. Legacy solutions fail in addressing these requirements. In this paper, we propose a service discovery protocol with security features, the Secure Pervasive Discovery Protocol. SPDPh is a fully distributed protocol in which services offered by devices can be discovered by others, without a central server. It is based on One Way hash Chains, as well as protection of confidential information, secure communications, or access control and compared this with Pervasive Discovery Protocol PDP
