A Survey of Security and Privacy Issues in V2X Communication Systems KU Leuven
Vehicle-to-Everything (V2X) communication is receiving growing attention from industry and academia as multiple pilot projects explore its capabilities and feasibility. With about 50% of global road vehicle exports coming from the European Union (EU), and within the context of EU legislation around security and data protection, V2X initiatives must consider security and privacy aspects across the system stack, in addition to road safety. ...
T-HIBE: A Novel Key Establishment Solution for Decentralized, Multi-Tenant IoT Systems KU Leuven
The Internet of Things (IoT) devices has evolved considerably in the past few years and is expected to grow exponentially in the next decade. This exponential growth makes key management in an IoT ecosystem very challenging. Traditional IoT systems are often centralized and grouped into an ecosystem. However, this type of centralized architecture is not always compatible with practical IoT deployments. This paper proposes T-HIBE, a secure key ...
NC-Max: Breaking the Security-Performance Tradeoff in Nakamoto Consensus KU Leuven
First implemented in Bitcoin, Nakamoto Consensus (NC) is the most influential consensus protocol in cryptocurrencies despite all the alternative protocols designed afterward. Nevertheless, NC is trapped by a security-performance tradeoff. While existing efforts mostly attempt to break this tradeoff via abandoning or adjusting NC's backbone protocol, we alternatively forward the relevance of the network layer. We identify and experimentally prove ...
