FIN553 Blockchain Security and Privacy focuses on information security and cryptography techniques underlying Fintech and blockchain technology. The course analyses different security concepts and examines how cryptographic techniques are used to realise different security objectives. It then looks at how the properties of a secure cryptographic function can be used to protect data integrity and user privacy in blockchain and Fintech applications, and evaluate the feasibility of the protocol design. It also discusses data integrity and confidentiality protection techniques, public-key infrastructure, peer-to-peer security, access control models and advanced cryptographic techniques to provide user privacy. Students will learn how to use open source security software such as Cryptool, GNU Privacy Guard, and the Python cryptography at an advanced level.
