Blockchain Based Credibility Verification Method for IoT Entities

Abstract EN

With the fast development of mobile Internet, Internet of Things (IoT) has been found in many important applications recently.

However, it still faces many challenges in security and privacy.

Blockchain (BC) technology, which underpins the cryptocurrency Bitcoin, has played an important role in the development of decentralized and data intensive applications running on millions of devices.

In this paper, to establish the relationship between IoT and BC for device credibility verification, we propose a framework with layers, intersect, and self-organization Blockchain Structures (BCS).

In this new framework, each BCS is organized by Blockchain technology.

We describe the credibility verification method and show how it provide the verification.

The efficiency and security analysis are also given in this paper, including its response time, storage efficiency, and verification.

The conducted experiments have been shown to demonstrate the validity of the proposed method in satisfying the credible requirement achieved by Blockchain technology and certain advantages in storage space and response time.
