With the rapid development of the Internet of Things (IoT) technology, it has been widely used in various fields. IoT device as an information collection unit can be built into an information management system with an information processing and storage unit composed of multiple servers. However, a large amount of sensitive data contained in IoT devices is transmitted in the system under the actual wireless network environment will cause a series of security issues and will become inefficient in the scenario where a large number of devices are concurrently accessed. If each device is individually authenticated, the authentication overhead is huge, and the network burden is excessive. Aiming at these problems, we propose a protocol that is efficient authentication for Internet of Things devices in information management systems. In the proposed scheme, aggregated certificateless signcryption is used to complete mutual authentication and encrypted transmission of data, and a cloud server is introduced to ensure service continuity and stability. This scheme is suitable for scenarios where large-scale IoT terminal devices are simultaneously connected to the information management system. It not only reduces the authentication overhead but also ensures the user privacy and data integrity. Through the experimental results and security analysis, it is indicated that the proposed scheme is suitable for information management systems.

信息管理系统中物联网设备的高效认证

随着物联网（IoT）技术的飞速发展，它在各个领域得到了广泛的应用。物联网设备作为信息采集单元，可以内置于由多台服务器组成的信息处理和存储单元的信息管理系统中。然而，在实际无线网络环境下，物联网设备中包含的大量敏感数据在系统中传输，会造成一系列安全问题，在大量设备同时访问的场景下会变得效率低下。如果每个设备单独认证，认证开销巨大，网络负担过重。针对这些问题，我们提出了一种对信息管理系统中的物联网设备进行有效认证的协议。该方案采用聚合无证书签密完成数据的相互认证和加密传输，并引入云服务器来保证服务的连续性和稳定性。该方案适用于大型物联网终端设备同时接入信息管理系统的场景。它不仅减少了认证开销，而且保证了用户隐私和数据完整性。通过实验结果和安全性分析，表明该方案适用于信息管理系统。该方案适用于大型物联网终端设备同时接入信息管理系统的场景。它不仅减少了认证开销，而且保证了用户隐私和数据完整性。通过实验结果和安全性分析，表明该方案适用于信息管理系统。该方案适用于大型物联网终端设备同时接入信息管理系统的场景。它不仅减少了认证开销，而且保证了用户隐私和数据完整性。通过实验结果和安全性分析，表明该方案适用于信息管理系统。
