This abstract presents a hierarchical Account aided Reputation Management system (ARM) to efficiently and effectively provide cooperation incentives. ARM builds a hierarchical locality aware distributed hash table (DHT) infrastructure for efficient and integrated operation of both reputation and price systems. The infrastructure helps to globally collect all node reputation information in the system, which can […]
A Hierarchical Account-Aided Reputation Management System To Efficiently And Effectively Provide Cooperation Incentives For Manets
In a MANET, nodes communicate with each other by routing data through relay nodes in a multihop manner. Thus, reliable communication is critical to the proper operation of MANETs. Encouraging cooperation and deterring selfish behaviors are important for proper operations of mobile ad hoc networks (MANETs). For this purpose, most previous efforts rely on either […]
A NOVEL SECURE AND DISTRIBUTED DATA DISCOVERY AND DISSEMINATION PROTOCOL IN WSN
The need of distributed data discovery and dissemination protocols is not completely new, but previous work did not address this need. We study the functional requirements of such protocols, and set their design objectives. Also, we identify the security vulnerabilities in previously proposed protocols. Based on the design objectives, we propose DiDrip. It is the […]
WIRELESS SENSOR NETWORKS WITH HOP-BY-HOP MESSAGE AUTHENTICATION AND SOURCE PRIVACY
In this abstract, we propose an unconditionally secure and efficient source anonymous message authentication (SAMA) scheme based on the optimal modified ElGamal signature (MES) scheme on elliptic curves. This MES scheme is secure against adaptive chosen-message attacks in the random oracle model. Our scheme enables the intermediate nodes to authenticate the message so that all […]
