Abstract
Purpose –The purpose of this paper is to propose a trusted security zone architecture that uses a
blockchain technologyto provide secure sharing of data in the security zone while maintainingthe integrity,
confidentialityand availability of data. The blockchain uses a distributednetwork to ensure data availability
and uses publicledgers to ensure the integrity and confidentiality of data.
Design/methodology/approach –The proposed architecture uses a blockchaintechnology to provide
secure sharing of data in the security zone whilemaintaining the integrity, confidentiality and availabilityof
data. The blockchainuses a distributed network to ensure data availability and uses public ledgersto ensure
the integrityand confidentiality of data.
Findings –Analysis of the proposed architecturewith a use case scenario demonstrates that it provides a
robust securitymeasure against unauthorized network intrusions.
Originality/value –Unlike the existing security zone, this paper adopts a method of storing data by
using blockchain. It meets the need to study integrated authentication management methods of future
research.

1. Introduction
Cryptocurrency has emerged in recent years, with the number of cryptocurrencies
available on the Internet increasing to more than 2000. Based on market capitalization,
Bitcoin is the largest blockchain network, followed by XPR, Ethereum and Bitcoin Cash.
The total market value of cryptocurrencies currently stands at around US$100bn and is
thus greater than the individual GDP of some `127 countries (CoinLore, 2019).
Blockchain, a core technology of cryptocurrency is a distributed public ledger system
that can be applied to various fields. Gartner also chose the blockchain as one of ten
strategic technologies in 2018 (Pettey, 2017). Since blockchain uses distributed public
ledgers, it provides easy management by providing data verification, including digital
content management and medical record tracking, through blockchain. In general, each
