Dr. Hitesh Tewari

Assistant Professor (Computer Science)
LLOYD INSTITUTE


Hitesh Tewari received his BA (Mod), MSc and PhD degrees in Computer Science from Trinity College Dublin, Ireland. Computer Networks, Security & Applied Cryptography inform the key direction of his research, and he has published numerous conference and journal papers in these areas. During his PhD, he developed a strong interest in electronic payments and co-authored a book, "Electronic Payment Systems", which has become a reference text in this area with the two editions having sold nearly 7,000 copies to date. In 2013, when he came across the Bitcoin protocol, which utilises Blockchains to eliminate the central point of dependency, such as a bank, in a payment network that he began to grasp the emerging interplay of electronic payment systems and decentralised networks. Since then, his research has focussed on decentralised privacy-preserving systems and the holistic application of Blockchain protocols in several areas beyond cryptocurrencies, such as personal privacy, public health, and the environment. In 2023, he was invited to become part of the Ripple University Blockchain Research Initiative (UBRI) Professorial Network.

Computer Networks, Security and Applied Cryptography inform the key directions of my research. During my PhD, I developed a strong interest in electronic payments and co-authored a book, "Electronic Payment Systems", which has sold 7,000 copies to date. In 2013, when I came across the Bitcoin protocol, which utilises Blockchains, to eliminate the central point of dependency in a payment network, I began to grasp the emerging interplay of electronic payments and decentralised networks. Since then, my research has focussed on Decentralized Privacy-Preserving Systems and the transformative application of Blockchains as outlined below: Development of Next-Gen Cryptocurrencies - The huge environmental toll associated with mining cryptocurrencies is poorly understood with Bitcoin mining surpassing the energy requirements of a country like Argentina. I am investigating energy efficient and high transaction throughput protocols for the next-generation of cryptocurrencies by designing novel consensus mechanisms. Safe and Decentralised Social Media - Social media platforms are rife with fake news and users are commonly subjected to abuse. I have developed a framework for a global public-key infrastructure and decentralised Internet, which ensures safe use of social media by securely identifying users. e-Health and Internet of Things (IoT) - I have developed a healthcare management ecosystem that allows a patient"s medical records to be stored securely and anonymously. I am also investigating the use of privacy-preserving techniques for constrained IoT devices in e-Health environments. I have been invited to become a member of the Ripple University Blockchain Research Initiative (UBRI) Professorial Network. I am investigating techniques to secure the Ripple Blockchain from quantum computing attacks, adding zero knowledge functionality, and making the Ripple Blockchain redactable to address GDPR issues. In partnership with the Electricity Supply Board (ESB), I am developing a real-time system for the trading of Guarantee of Origin Certificates (GOs), which identifies electricity coming from renewable sources. This project has enabled me to explore the related areas of Power Grids and Smart Cities. As highlighted above, all key aspects of my research are highly innovative, multi-disciplinary, cutting-edge, and address key societal and environmental challenges which are closely aligned with the College Strategic Plan 2020-25 (Priority 2: Research for Impact and Sustainability).
