Autonomous Trust Establishment1

چکیده
Trust establishment in networks is the essential foundation for follow-on security mechanisms, such as key management and secure transmission. In this paper, we concentrate on self-organized, distributed and resource-constraint networks which pose formidable challenges on trust establishment due to lack of infrastructure and centralized servers. We model our trust establishment strategy as a local voting scheme and discuss its long run behavior. More specifically, we investigate the dynamic evolution of trust within the network, i.e. how trust spreads among nodes, via analyzing its convergence behavior. By theoretical analysis based on graph theory, we also find the conditions under which trust spreads to a maximum set of nodes and parameters that speed up or slow down this transition. keywords: Network, Trust Establishment, Security, Graph Theory

A Perspective on Trust, Security and Autonomous Systems
We argue that the advent of autonomous systems profoundly changes the nature of security arguments. Whereas security in socio-economic systems fundamentally relies on human beings to be the ultimate resolvers of trust decisions, this can no longer be the case for truly autonomous systems. In order to understand how to build such autonomous systems there is a need to create a logical theory of t...
متن کاملAnalyzing Human Trust of Autonomous Systems in Hazardous Environments
Autonomous systems are becoming more prevalent in our everyday lives. From agent software that collects news for us or bids for us in online auctions to robots that vacuum our floors and may help care for us when we grow old, autonomous agents promise to play a greater role in our lives in the future. Yet, there is ample evidence that many people do not trust autonomous systems – especially in ...
متن کاملAutonomous Agents and Human Interpersonal Trust: Can We Engineer a Human-Machine Social Interface for Trust?
There is a recognized need to employ autonomous agents in domains that are not amenable to conventional automation and/or which humans find difficult, dangerous, or undesirable to perform. These include time-critical and mission-critical applications in health, defense, transportation, and industry, where the consequences of failure can be catastrophic. A prerequisite for such applications is t...
متن کاملCognitive Reasoning and Trust in Human-Robot Interactions
We are witnessing accelerating technological advances in autonomous systems, of which driverless cars and home-assistive robots are prominent examples. As mobile autonomy becomes embedded in our society, we increasingly often depend on decisions made by mobile autonomous robots and interact with them socially. Key questions that need to be asked are how to ensure safety and trust in such intera...
