Survivability of Sensors with Key and Trust Management

چکیده
Weiser (1991) envisioned a ubiquitous computing world where intelligent computing and communicating devices are pervasive and woven into the fabrics of every day artifacts. His vision is being materialised: the market of large scale sensors and hand-held devices networks has been gaining momentum. However, one may question whether or not these computing and communicating entities will be able to survive in an open environment. These computing entities are no more protected by a physical security perimeter; foreign, potentially malicious, entities can tamper with them. Another challenge for the real deployment of these networks of sensors and portable devices is to provide them AbstrAct

A Multi Objective Graph Based Model for Analyzing Survivability of Vulnerable Networks
In the various fields of disaster management, choosing the best location for the Emergency Support & Supply Service Centers (ESSSCs) and the survivability of the network that provides the links between ESSSCs and their environment has a great role to be paid enough attention. This paper introduces a graph based model to measure the survivability of the linking's network. By values computed for ...
متن کاملThe Florida State University College of Arts and Sciences Trust Management in Mobile Wireless Networks: Security and Survivability
In this dissertation we study the security and survivability of wireless mobile network systems in two distinct threat models: the Byzantine threat model and the selfish node threat model. Wireless mobile networks are collections of self-organizing mobile nodes with dynamic topologies and have no fixed infrastructure. Because of their dynamic ad hoc nature, these networks are particularly vulne...

The Internet of Things (IoT), is a new concept that its emergence has caused ubiquity of sensors in the human life. All data are collected, processed, and transmitted by these sensors. As the number of sensors increases, the first challenge in establishing a secure connection is authentication between sensors. Anonymity, lightweight, and trust between entities are other main issues that shoul...
متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
متن کاملRandom Key Pre-Distribution Techniques against Sybil Attacks
Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
