由于电信技术在远程医疗服务中的引入，无线和移动的网络的迅速发展刺激了移动的电子医疗系统的广泛应用。然而，安全性是一项基本的系统要求，因为许多患者在通过开放无线渠道发布个人信息时存在隐私问题。出于这个原因，本研究讨论了无线和普及的数据通信的特点和安全问题，一个无处不在的和移动的医疗保健系统，其中包括一些移动的设备和传感器连接到病人。这些设备形成移动的自组织传感器网络，并收集发送到医院或医疗保健中心进行监测的数据。在此基础上，本文提出了一种新的信任评估模型。然后，我们提出了一个安全的组播策略，采用信任，以评估每个节点的行为，使只有值得信赖的节点被允许参与通信，而恶意节点的不当行为被有效地防止。我们分析了我们的组播方案的安全特性，并评估其性能的基础上模拟实验。我们的实验结果表明，我们的计划不仅实现了必要的数据传输在移动的环境中，但也提供了更多的安全性与合理的额外开销很少。
Due to the introduction of telecommunication technologies in telemedicine services, the expeditious development of wireless and mobile networks has stimulated wide applications of mobile electronic healthcare systems. However, security is an essential system requirement since many patients have privacy concerns when it comes to releasing their personal information over the open wireless channels. For this reason, this study discusses the characteristics and security issues with wireless and pervasive data communications for a ubiquitous and mobile healthcare system which consists of a number of mobile devices and sensors attached to a patient. These devices form a mobile ad hoc sensor network and collect data that are sent to a hospital or healthcare center for monitoring. Subsequently, this paper discusses the innovation and design of a novel trust evaluation model. We then propose a secure multicast strategy that employs trust in order to evaluate the behavior of each node, so that only trustworthy nodes are allowed to participate in communications, while the misbehavior of malicious nodes is effectively prevented. We analyze the security properties of our multicast scheme and evaluate its performance based on simulation experiments. Our experimental results demonstrate that our scheme not only achieves the necessary data transmission in mobile environments, but also provides more security with reasonably little additional overhead.
