Security Attacks in Named Data Networking of Things and a Blockchain Solution

The Internet of Things (IoT) is visioned to connect everything in the world by a common networking technique. In spite that Internet protocol is the most prevailing networking solution, it is difficult to adapt to loT which is born with scalability, heterogeneity, and dynamics. Thanks to the content-centric communication paradigm, it exerts data-naming strategy to incorporate the heterogeneity and dynamics so as to apply for IoT, composing Named Data Networking (NDN) of Things. However, the paradigm also introduces new types of security attacks. In this paper, the NDN of Things architecture will be illustrated and the security analysis is conducted. Furthermore, the potential security attacks of NDN of Things are categorized and the performance impact caused by security attacks is evaluated. Finally, the solutions for NDN of Things security attacks are discussed and a blockchain solution is illustrated.
