IOT Security Issues Via Blockchain

Blockchain from the Perspective of Privacy and Anonymisation: A Systematic Literature Review

“…We found a need to provide standards [27], especially in the area of IoT [33,49], that will encourage the exchange of data between devices from different manufacturers and that will adequately address issues such as possible device spoofing and authentication [8,36] as well as increase the degree of reliability in the exchange of data between devices. This is related to the proposal we found in [23] to increase the level of confidentiality of shared information.…”

“…The first references we found about anonymisation would be through pseudonymisation [7], which consists of removing some of the information necessary to identify an entity. Although, in [31,32,49] they claim that blockchain does not guarantee totally anonymous transactions, even that through its pseudonym the transactions could be traced. In [9], the authors mention that distributed consensus and anonymity are two important features of blockchain.…”

“…Cryptography is very important to ensure the anonymisation of the entities participating in the blockchain, finding [47] different levels of anonymisation possible depending on the cryptographic functions used. One of the implementations of blockchain technology is through pseudonymisation [7,31,49,51]. A technique in which the identity is often hidden behind a public key, although other transaction attributes are shared publicly.…”

“…IoT. The blockchain technology has revolutionised the IoT [31,49] with its efficiency and scalability, although it tries to give solution to the way in which the different devices that intervene are related creating an environment of reliability and security as well as the transfer of information between devices in a reliable way; however, there are unresolved limitations to improving the scalability of IoT devices [52]; this is being approached from a new perspective of distributed ledger under the IOTA project. The work in [33] highlights the need to develop a standard for sharing IoT data sets in order to take advantage of the blockchain potential to facilitate the safe exchange of data as well as to secure the IoT system itself.…”

“…The work in [33] highlights the need to develop a standard for sharing IoT data sets in order to take advantage of the blockchain potential to facilitate the safe exchange of data as well as to secure the IoT system itself. One of the most important problems to be solved [8,49] would be device impersonation, false authentication or unreliability that could occur in the data exchange. This can be a security breach, which is a prerequisite for implementing privacy.…”
