Efficient Authentication for Internet of Things Devices in Information Management Systems

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