I am a cryptographer focusing on the theoretical and the applied aspects of cryptographic protocols. I am particularly interested in unconditional privacy, including topics such as: quantum cryptography; protocols based on noise; authentication based on signal reconciliation; election and mixing protocols; general two- and multi-party computation; privacy-preserving data mining etc. Many of these protocol borrow techniques from information theory and coding theory. I have a Master’s in mathematics from the Universiteit van Amsterdam (1985) and a PhD in Informatics from the Université de Montréal (1998). From August 2008 until February 2011 I was an Assistant Professor at the Universidade Federal de Ouro Preto. Since March 2011 I moved to the Universidade Federal de Minas Gerais.
