Sustainable, wearable, and eco-friendly electronic textiles (2024)
Journal Article

Wearable electronic textiles (e‐textiles) with embedded electronics offer promising solutions for unobtrusive, real‐time health monitoring, enhancing healthcare efficiency. However, their adoption is limited by performance and sustainability challeng... Read More about Sustainable, wearable, and eco-friendly electronic textiles.

Toward sustainable wearable electronic textiles (2022)
Journal Article

Smart wearable electronic textiles (e-textiles) that can detect and differentiate multiple stimuli, while also collecting and storing the diverse array of data signals using highly innovative, multifunctional, and intelligent garments, are of great v...

Security properties of light clients on the ethereum blockchain (2020)
Journal Article

Ethereum is a decentralized blockchain, known as being the second most popular public blockchain after Bitcoin. Since Ethereum is decentralised the canonical state is determined by the Ethereum network participants via a consensus mechanism without a...

Towards fairness and decentralisation in modern cryptocurrencies (2019)
Thesis

The thesis examines and improves upon the properties of both fairness and decentralisation
in modern cryptocurrencies, re-examining public key infrastructure, client puzzles and useful
proofs of work in the blockchain context. The thesis also dev... Read More about Towards fairness and decentralisation in modern cryptocurrencies.

Zero-Knowledge Proof of Decryption for FHE Ciphertexts (2018)
Journal Article

Valuable Puzzles for Proofs-of-Work (2018)
Presentation / Conference Contribution

Proof-of-work (PoW) is used as the consensus mechanism in most cryptocurrencies. PoW-based puzzles play an important part in the operation and security of a cryptocurrency, but come at a considerable energy cost. One approach to the problem of energy...

Graphchain: A blockchain-free scalable decentralised ledger (2018)
Presentation / Conference Contribution

© 2018 Copyright held by the owner/author(s). Blockchain-based replicated ledgers, pioneered in Bitcoin, are effective against double spending, but inherently attract centralised mining pools and incompressible transaction delays. We propose a framew... Read More about Graphchain: A blockchain-free scalable decentralised ledger.

Key recovery: Inert and public (2017)
Presentation / Conference Contribution

We propose a public key infrastructure framework, inspired by modern distributed cryptocurrencies, that allows for tunable key escrow, where the availability of key escrow is only provided under strict conditions and enforced through cryptographic me...

CARIBE: Cascaded IBE for maximum flexibility and user-side control (2017)
Presentation / Conference Contribution

© Springer International Publishing AG 2017. Mass surveillance and a lack of end-user encryption, coupled with a growing demand for key escrow under legal oversight and certificate authority security concerns, raise the question of the appropriatenes...

Bitcoin unchained (2017)
Journal Article

Bitcoin’s distributed ledger is an innovative way of solving the double spending problem in a decentralised system. However, it causes incompressible transaction delays and incentivises consolidation of mining power. We ask, is it possible to elimina... Read More about Bitcoin unchained.

Fair client puzzles from the Bitcoin blockchain (2016)
Presentation / Conference Contribution

Client puzzles have been proposed as a mechanism for proving legitimate intentions by providing “proofs of work”, which can be applied to discourage malicious usage of resources. A typical problem of puzzle constructions is the difference in expected... Read More about Fair client puzzles from the Bitcoin blockchain.

A guide to fully homomorphic encryption (2015)
Journal Article

Fully homomorphic encryption (FHE) has been dubbed the holy grail of cryptography, an elusive goal which could solve the IT world’s problems of security and trust. Research in the area exploded after 2009 when Craig Gentry showed that FHE can be real... Read More about A guide to fully homomorphic encryption.
