面向资源受限环境的物联网节点安全认证模型与隐私保护机制

As a low-cost, simple Internet of Things(IoT) and pervasive computing support technology, the security and privacy protection of RFID is the biggest challenge which faces in practical applications. Therefore, how to enhance or improve the security of low-cost RFID system with limited resources of IoT nodes and reduce the cost of implementation has become one of the research hotspots in the field of IoT technology. The IoT not only has the same security problems as traditional networks, but also has its own security characteristics on authentication and privacy protection of heterogeneous networks. How to design and implement secure, efficient and low-cost authentication and identification protocols for IoT nodes with limited resources and environment, especially low-cost RFID resources, is the biggest challenge in the application of IoT and RFID. This project intends to explore and study the security authentication model and mechanism for protecting the privacy of low-cost RFID tag information in the IoT from the aspects of low-cost RFID tag security authentication mechanism or protocol and formal model of security and attack. The research results will have important academic significance and good application prospects.

RFID作为一种成本低廉、实施简单的物联网和普适计算支撑技术，其安全和隐私保障是它在实际应用中面临的最大挑战。因此如何增强或提高物联网节点资源受限低成本RFID系统的安全度、降低实现成本，已成为当前物联网技术领域的研究热点之一。物联网不仅存在与传统网络同样的安全问题，还在异构网络的认证、隐私保护等问题上有其自身的安全特点。如何针对资源环境受限的物联网节点，特别是低成本RFID资源受限的特点，设计和实现安全、高效、低开销的安全认证识别协议，则是物联网及RFID应用中面临的最大挑战。本项目拟从物联网中低成本RFID标签安全认证机制、协议和安全与攻击形式化模型等方面探索和研究保护物联网中低成本RFID标签信息隐私的安全认证模型和机制，其研究成果将具有重要的学术意义和很好的应用前景。

由于物联网应用比一般的网络更易受侵扰，传统网络的安全措施不能提供可靠的安全保障，使得IoT的安全问题更具有特殊性和复杂性。因此随着RFID的大规模应用，其在安全与隐私方面也暴露出的问题日益严重。项目针对资源环境受限的物联网节点，特别是低成本RFID资源受限的特点，设计和实现安全、高效、低开销的安全认证识别协议。从物联网中低成本RFID标签安全认证机制、协议和安全与攻击形式化模型等方面探索和研究保护物联网中低成本RFID标签信息隐私的安全认证模型和攻击者模型，从而达到保护资源受限的低成本IoT节点RFID标签信息隐私的目的。
