Over the past few years, demand for hand-held computers and smartphones has been rising significantly. The unprecedented widespread adoptionof mobile computing devices, coupled with substantial advances in wireless networking technologies, have created the infrastructure needed to support the anywhere-anytime computing paradigm. In a society that has already become used to, and dependent on, the rapid access to information sourcesand services, mostly as a consequence of experience with the fixed Internet, the provision of ubiquitous computing services will appear extremely attractive.Consumer demand is set to raise, and so is the number and range of services on offer. Quite inevitably, the expected commercial return will attract malicious subjects as well, that will exploit the very nature of pervasive computing (e.g., the relative ease with which services and information can be accessed, the anonymity of the entities we interact with, the speed with which new entities come into reach while others disappear, etc.) to perpetrate attacks and make unjust financial gains. Being able to decide who canbe trusted in this plethora of opportunistically connected devices and services will thus become key to the success of ubiquitous computing. In designing a trust management model for pervasive systems, we recognise two major requirements that demand investigation: the need for models that mimic human trust reasoning as faithfully as possible, and the need for the formal elicitation of metrics that can be used to assess and compare the qualityof trust models. We intend to propose new models to tackle the problem of distributed trust management in pervasive systems, by means of a combination of group dynamics, microeconomic theory, belief theory,and social network theory. We will implement the models and assess their quality with respect to the newly defined metrics, by means of simulation andcase studies.

在过去几年中，对手持电脑和智能手机的需求一直在显著上升。移动的计算设备的前所未有的广泛采用，加上无线网络技术的巨大进步，创造了支持随时随地计算范式所需的基础设施。在一个已经习惯于并依赖于快速获取信息源和服务的社会中，主要是由于固定互联网的经验，无处不在的计算服务的提供将显得非常有吸引力。消费者的需求将增加，提供的服务的数量和范围也将增加。不可避免的是，预期的商业回报也将吸引恶意主体，这将利用普适计算的本质（例如，可以访问服务和信息的相对容易性、与我们交互的实体的匿名性、新实体进入而其他实体消失的速度等）。实施攻击并获取不正当的经济利益。因此，能够决定谁可以在这过多的机会主义连接的设备和服务中信任，将成为无处不在计算成功的关键。在设计一个普遍的系统的信任管理模型，我们认识到两个主要的要求，需要调查：需要模型，模仿人类的信任推理尽可能忠实，并需要正式的指标，可用于评估和比较qualityof信任模型的启发。我们打算提出新的模型来解决问题的分布式信任管理在普适系统中，通过组合的群体动力学，微观经济理论，信仰理论和社会网络理论。我们将通过模拟和案例研究的方式，实施这些模型，并根据新定义的指标评估它们的质量。
