Security Services Using Blockchain Technology

Recently, blockchain technology has attracted tremendous interest from both academia and industry. The technology currently spans several applications that are popular and driving networking research. Such applications include healthcare, Internet of Things (IoT), and cloud storage. Generally, blockchain technology has proven its potential in any application that currently requires a centralized ledger. 

Among the blockchains’ promising applications are network monitoring and security services, including authentication, confidentiality, privacy, integrity, and provenance. Currently, these services are provided by trusted third-party brokers or using inefficient distributed approaches. As a result, security is a significant challenge for current applications. On the other hand, the blockchain technology can provide security guarantees that resolve many traditional difficulties in addition to providing a fully distributed, provably secure, and consensus solution.
