Secure Identifier Management Based on Blockchain Technology in NDN Environment

Abstract

With the recent increase in the number of IoT devices and the development of centralized management systems, risks in cyber space, including personal information phishing, malicious code infection, hacking, and DDos attack, are becoming major issues in the real world. The recently developed distributed data management technology, blockchain, provides reliability in transactions without the intervention of a third party. This new technology, blockchain, promotes integrity and reliability of transaction records by allowing for all network participants to jointly own and verify data, which was previously done by a central server. Due to distributed data management, the technology can reduce brokerage fees and construction costs, and guarantees high levels of integrity and security of data. This paper examines the effective identifier management using blockchain technology under the named data networking environment. The proposed system does not expose a specific user's identifier by creating a transaction using the content name of the identifier. The identifier can be safely stored and managed through such an identifier split management technique.
