Project AbstractWireless sensor networks have received tremendous attention in the past few years and have been envisioned as the key enabling technology for the future ubiquitous computing environment. To successfully realize such a vision, mechanisms that allow a large number of (mobile) users, in addition to a small number of (fixed) sink nodes, to securely and efficiently access the wireless sensor networks are indispensable. This project is to develop security mechanisms to secure broadcast/multicast communications in a multi-user wireless sensor networks since broadcast/multicast is the most important communication type when a user attempts to access a wireless sensor network, either to retrieve desired information or to request some actions taken by some sensor/actuator nodes. More specifically, this project is focused on two major security tasks: broadcast/multicast authentication and encryption. The first task is on multi-user broadcast authentication, which aims to provide effective, efficient, scalable, and secure broadcast authentication mechanisms that support a large number of mobile users to broadcast to a wireless sensor network anytime from anywhere in the network. Efficient cryptographic tools will be integrated with public key operations to minimize the overall computation and communication overhead and achieve higher security strength for various application scenarios. The second task is on semantics-based dynamic multicast encryption, which aims to provide a more efficient solution to handle the group membership dynamics. The idea is based on a novel semantics-based elementary group concept and efficient multicast encryption schemes that integrate energy-efficient geographical multicast routing techniques will be devised.

在过去的几年中，Project AbstractWireless传感器网络受到了极大的关注，并被设想为未来无处不在的计算环境的关键技术。为了成功实现这样的愿景，除了少量（固定的）水槽节点外，还允许大量（移动）用户的机制安全有效地访问无线传感器网络是必不可少的。该项目将开发安全机制，以在多用户无线传感器网络中保护广播/多播通信，因为当用户试图访问无线传感器网络时，广播/多播是最重要的通信类型，以检索所需的信息或要求某些传感器/执行器节点采取的某些操作。更具体地说，该项目集中在两个主要的安全任务上：广播/多播身份验证和加密。第一个任务是在多用户广播身份验证上，该验证旨在提供有效，高效，可扩展和安全的广播身份验证机制，这些身份验证机制支持大量移动用户，以随时随地从网络中的任何地方广播到无线传感器网络。有效的加密工具将与公共密钥操作集成，以最大程度地减少整体计算和通信开销，并为各种应用程序方案实现更高的安全强度。第二个任务是基于语义的动态多播加密，该加密旨在提供更有效的解决方案来处理组成员的动态。该想法基于一种基于语义的新型基础群体概念和有效的多播加密方案，该方案将设计整合能节能地理多播路由技术。
