An Architecture for Accountable Anonymous Access in the Internet-of-Things Network

This is the author accepted manuscript. The final version is available from IEEE via the DOI in this record.With the rapid development of the Internet, more and more devices are being connected to the Internet, making up the Internet-of-Things (IoT). The accountability and privacy are two important but contradictory factors to ensure the security of IoT networks. How to provide an accountable anonymous access to IoT networks is a challenging task. Since the IoT network is largely driven by services, in this paper we propose a new and efficient architecture to achieve accountable anonymous access to IoT networks based on services. In this architecture, a self-certifying identifier is proposed to efficiently identify a service. The efficiency and overhead of the proposed architecture are evaluated by virtue of the real trace collected from an Internet service provider. The experimental results show that the proposed architecture could efficiently balance accountability and privacy with acceptable overheads.This work is partially supported by the National Key Technology Research and Development Program (No. 2017YFB0801801), the National Science and Technology Major Project of the Ministry of Science and Technology of China (No. 2017ZX03001019), and the National Natural Science Foundation of China (No. 61672490 and No. 61303241)
