Jeong, Yoon Hwan (author)In order to combat increasing spam calls, many applications are developed and downloaded to block those calls. Some studies about performance of the applications were previously conducted, however, the actual processes the applications go through to intercept and block the spam calls are not well studied. This research presents a method to...bachelor thesis 2022

Yüksel, Akif (author)Kyber is a Decentralized Finance (DeFi) system which runs on the Ethereum blockchain. DeFi aims to remove centralized intermediaries such as Market Makers. An Automated Market Maker (AMM), implemented in a smart contract, is a decentralized version of these. Kyber's Dynamic Market Maker (DMM) is a next-generation AMM which solves two issues:...bachelor thesis 2021

de Los Santos Subirats, Alex (author)Software-Defined Networks (SDNs) are a promising new network design paradigm that allows for better control of the network. But as with any new software implementation, there are new security concerns that arise. In the past there have been various papers covering specific side-channel attacks on SDNs; most of them consist of either using time...bachelor thesis 2022

Bubberman, Wolf (author)The Ripple XRP Ledger network hosts a cryptocurrency called XRP which uses the TLS protocol to send messages between nodes. It is crucial that the network is tested against attacks to ensure its security. The Ripple XRP Ledger could be vulnerable to a Man-in-the-Middle (MITM) attack. This MITM attack is an attack which can intercept and modify...bachelor thesis 2020

Parkin, S.E. (author), Arnell, Simon (author), Ward, Jeremy (author)Leaders of organisations must make investment decisions relating to the security of their organisation. This often happens through consultation with a security specialist. Consultations may be regarded as conversations taking place in a trading zone between the two domains. We propose that supporting the trading zone is a route to sustainable,...conference paper 2021

Presekal, A. (author), Stefanov, Alexandru (author), Subramaniam Rajkumar, Vetrivel (author), Palensky, P. (author)The cyber attacks in Ukraine in 2015 and 2016 demonstrated the vulnerability of electrical power grids to cyber threats. They highlighted the significance of Operational Technology (OT) communication-based anomaly detection. Many anomaly detection methods are based on real-time traffic monitoring, i.e., Intrusion Detection Systems (IDS) that may...conference paper 2023
