Trust is an essential feature of any system where entities have to collaborate among them. Trust can assist entities making decisions about what is the best entity for establishing a certain collaboration. It would be desirable to simulate behaviour of users as in social environments where they tend to establish relationships or to trust users who have common interests or share some of their op...

We propose and analyze trust-based cooperative spectrum sensing data fusion schemes against spectrum sensing data falsification attacks in cognitive radio networks. We first consider the case in which a centralized data fusion center is in place for decision making. Then we extend it to the case in which the data fusion center is absent leading to autonomous and distributed decision making. Our...

Understanding how human beings delegate tasks to trustees when presented with reputation information is important for building trust models for human-agent collectives. However, there is a lack of suitable platforms for building large scale datasets on this topic. We describe a demonstration of a multi-agent game for training students in the practice of Agile software engineering. Through inter...

Cloud sourcing consists of outsourcing data, services and infrastructure to cloud providers. Even when this outsourcing model brings advantages to cloud customers, new threats also arise as sensitive data and critical IT services are beyond customers’ control. When an organization considers moving to the cloud, IT decision makers must select a cloud provider and must decide which parts of the o...

This paper argues that respect, defined as esteem for another person’s abilities and character, is an important factor in successful collaborative work. In making this claim, trust is used as the springboard for why interpersonal attitudes are important in the first place. Respect is first differentiated from trust conceptually, and then examined empirically in simulated top management teams. I...

The open and dynamic nature of modern distributed systems and pervasive environments presents significant challenges to security management. One solution may be trust management which utilises the notion of trust in order to specify and interpret security policies and make decisions on security-related actions. Most trust management systems assume monotonicity where additional information can o...

Node misbehavior due to selfish or malicious intention could significantly degrade the performance of MANET because most existing routing protocols in MANET are aiming at finding most efficiency path. To deal with misbehavior in MANET, an incentive mechanism should be integrated into routing decision-making. In this paper firstly we review existing techniques for secure routing, and then propos...

Trust management has received a lot of attention recently as it is an important component of decision making for electronic commerce, Internet interactions and electronic contract negotiation. However, appropriate tools are needed to effectively specify and manage trust relationships. They should facilitate the analysis of trust specification for conflicts and should enable information on risk ...

Recent advances in the fields of robotics, cyborg development, moral psychology, trust, multi agent-based systems and socionics have raised the need for a better understanding of ethics, moral reasoning, judgment and decision-making within the system of man and machines. Here we seek to understand key research questions concerning the interplay of ethical trust at the individual level and the s...

Managing workplace safety in the technology work environment has traditionally focused on factors such as physical design, machinery operations and other hardware counter-measures. Cognitive-based human factors have not seen a strong emphasis by safety and technology researchers. This is beginning to change as investigators have begun to examine how the management of human factors could impact ...
