NB-IoT(Narrow Band Internet of Things)是基于蜂窝窄带物联网的一种新兴技术,是物联网的一个重要分支.随着NB-IoT终端设备的规模不断增大,物联网安全面临数据泄露、中间人攻击等安全威胁.本论文针对NB-IoT技术的数据安全传输研究,从物联网终端安全和应用服务安全两方面进行分析,结合密码技术给出了NB-IoT系统安全模型,提出了基于物联网应用层数据信源加密传输机制,给出了轻量级身份认证协议和数据加密传输协议,论证了该方案的安全性,通过实验验证了所提方案的可行性和适用性.
Application Layer Secure Data Transmission Mechanism based on NB-IoT
As an emerging technology of cellular-based narrowband IoT,NB-IoT (Narrow Band Internet of Thing) is an important branch of IoT. With the increase of NB-IoT terminal amount,IoT security faces the threats such as data breach,man-in-the-middle attack,etc. In this paper,secure data trans-mission of the NB-IoT is studied. IoT terminal security and application service security are analyzed. Combining the cryptology,a NB-IoT system security model is presented and an IoT application layer da-ta source encryption transmission mechanism is proposed. A lightweight identity authentication protocol and a data encryption transmission protocol are presented. Security of the solutions are demonstrated and the feasibility and applicability are validated by experiments.
