The Internet of Things is becoming a critical subject nowadays and along with an increasing adoption of ubiquitous computing devices security becomes an issue which must be approached in different application contexts. One notion that gains traction along with the IoT (Internet of Things) paradigm is the social context of embedded devices. This paper proposes a participatory verification security...
Internet of Things (IoT) can connect a large numberof things (or agents) through communication networks for varioustypes of applications. Like in many other applications, it isvery important for all the agents in IoT systems to collaboratewith each other following predefined protocols. In this paper, we proposed a general trust management framework aiming tohelp agents to evaluate their partners'...
Wireless communication technology and the electronic systems advancements have laid the foundation of the wireless sensor network which achieves the growth of low-cost, low power and multi-functional sensor nodes which can be deployed on a single chip to communicate over a short range. The sensor node consists of sensing elements, actuator and a limited source of energy as battery. The major problem...
The technological advancement in the field of wireless communication and electronic systems have provided the opportunity for the wireless sensor network to achieve the development of low-cost, low power and multi-functional sensor nodes which can be placed on a single chip and can communicate over a short distance. The critical issue faced by wireless sensor networks is the efficient energy utilization...
In a military tactical network where a trust authority (e.g., a commander) makes a decision during a mission, assessing the trustworthiness of participating entities accurately is critical to mission success. In this work, we propose a trust-based reputation management scheme, called GlobalTrust, for minimizing false decisions on the reputation of nodes in the network. In the proposed scheme, nodes...
Today's VANET applications are vastly focused towards fulfilling users' requirements on road and making their journey safe and comfortable. In particular, safety applications will provide secure information to users and introduce mechanisms to help reduce the death rate due to road accidents. The most important aspect in such environment is the integrity of this safety information; it must be at all...
Trusted Layered Sensing has evolved from an Air Force Research Laboratory (AFRL) initiative to a vision now shared across government research agencies, industry, and academia. “Trust” is viewed as the most critical issue affecting Layered Sensing architectures since it's impossible to build Situational Awareness (SA) out of inaccurate, misleading, or denied information. Sensing systems (SS) consist...
In wireless sensor networks, malicious sensor nodes send false data reports to distort aggregation results. Existing trust systems rely on general reputation to mitigate the effect of this attack. This paper presents a novel reliable data aggregation protocol, called RDAT, which is based on the concept of functional reputation. Functional reputation enables data aggregators to evaluate each type of...
