Decentralized Cryptography: Cryptocurrencies, Privacy and Multi-Party Security

Topics for Bachelor Students

  • Privacy-Preserving Record Linkage

Record linkage is a crucial step in many database applications. At the same time, record linkage can be a privacy issue. To what degree is it possible to support record linkage while maintaining a well-specified and quantifiable amount of privacy for the user?

 

Topics for Master Students

In recent years, the idea of hash-based cryptocurrencies, such as Bitcoin, has taken off. A disadvantage of Bitcoin is the dependency on cryptographic "proofs of work", which are, de facto, a "proof of power consumption" and CO2-emission. Thus, we study environmentally more friendly alternatives, such as "proofs of storage".
