Internet of things (IoT) is a technology that can collect the data sensed by the devices for the further real-time services. Using the technique of cloud computing to assist IoT devices in data storing can eliminate the disadvantage of the constrained local storage and computing capability. However, the complex network environment makes cloud servers vulnerable to attacks, and adversaries pretend to be legal IoT clients trying to access the cloud server. Hence, it is necessary to provide a mechanism of mutual authentication for the cloud system to enhance the storage security. In this paper, a secure mutual authentication is proposed for cloud-assisted IoT. Note that the technique of chameleon hash signature is used to construct the authentication. Moreover, the proposed scheme can provide storage checking with the assist of a fully-trusted entity, which highly improves the checking fairness and efficiency. Security analysis proves that the proposed scheme in this paper is correct. Performance analysis demonstrates that the proposed scheme can be performed with high efficiency.
物联网（IoT）是一种能够收集设备感知数据以提供进一步实时服务的技术。利用云计算技术协助物联网设备进行数据存储，可以消除本地存储和计算能力受限的缺点。然而，复杂的网络环境使云服务器容易受到攻击，攻击者会伪装成合法的物联网客户端试图访问云服务器。因此，有必要为云系统提供一种相互认证机制，以增强存储安全性。本文针对云辅助物联网提出了一种安全的相互认证方法。请注意，变色龙哈希签名技术用于构建认证。此外，所提出的方案可以在一个完全可信实体的协助下提供存储检查，这大大提高了检查的公平性和效率。安全性分析证明本文提出的方案是正确的。性能分析表明所提出的方案可以高效执行。
