With the rapid development of Internet of Things (IoT) information technology, the IoT has become a key infrastructure for telemedicine, smart home, and intelligent transportation. One of the key technologies for these applications is information sharing and interoperation among multiple domains. However, the security and privacy issues of multidomain interaction face severe security challenges. Aiming at these problems, an certificateless multidomain authentication technology is proposed for IoT. Bilinear mapping and short signature technology are used to realize mutual authentication among entities in different domains, which protects secure data sharing and secure interoperability among domains. Certificateless multidomain authentication can avoid inherent security risks of key escrow in existing identity-based authentication. And it also solves complex certificate management and network bottlenecks problems in traditional certificate-based authentication. The proof and analysis show that the proposed scheme has good security and performance, it supports anonymous authentication among entities, and it is also suitable for large-scale distributed network security alliance authentication mechanism.

物联网多域安全认证

随着物联网（IoT）信息技术的快速发展，物联网已成为远程医疗、智能家居和智能交通的关键基础设施。这些应用程序的关键技术之一是多个域之间的信息共享和互操作。然而，多域交互的安全和隐私问题面临严峻的安全挑战。针对这些问题，提出了一种面向物联网的无证书多域认证技术。采用双线性映射和短签名技术实现不同域实体之间的相互认证，保障域间数据安全共享和安全互操作。无证书多域认证可以避免现有基于身份的认证中密钥托管的固有安全风险。同时也解决了传统基于证书的认证中复杂的证书管理和网络瓶颈问题。证明和分析表明，该方案具有良好的安全性和性能，支持实体间匿名认证，适用于大规模分布式网络安全联盟认证机制。
