Lukas Aumayr - A protocol has been developed at TU Wien that makes transactions with cryptocurrencies such as Bitcoin faster and more secure. Cryptocurrencies like Bitcoin are becoming increasingly popular. At first glance, they have many advantages: Transactions are usually anonymous, fast and inexpensive. But sometimes there are problems with them. In certain situations, fraud is possible, users can discover information about other users that should be kept secret, and sometimes delays occur. The research unit "Security and Privacy" at TU Wien (Lukas Aumayr and his supervisor Prof. Matteo Maffei) in collaboration with the IMDEA Software Institute (Prof. Pedro Moreno-Sanchez, previously postdoc at TU Wien) and the Purdue University (Prof. Aniket Kate) analyzed these problems and developed an improved protocol. It has now been published and will be presented this year at the USENIX Security Symposium - one of the "Big Four" IT security conferences worldwide, which are considered very prestigious.
