Towards improved trust in threat intelligence sharing using blockchain and trusted computing

Abstract

Threat Intelligence Sharing is one of the most promising approaches to resist ever-growing cyber attacks. Pressing challenges including concerns about trust, privacy, negative publicity, policy/legal issues and expense of sharing inhibit e ective sharing. Among all these sharing requirements, open trust issues are most crucial and fundamental prerequisites. Blockchain Technology has been widely adapted in data sharing market such as IoT Data sharing, Health Information sharing and so on. Trusted Computing provides an isolated secure trustworthy execution environment. This thesis AIMs to investigate the use of Blockchain Technology and Trusted Computing as a mechanism to address open trust issues of threat intelligence sharing.
