Tønnes Brekne

Until recently, I was a post.doc. at the Centre for Quantifiable Quality of Service in Communication Systems at the Norwegian University of Science and Technology. I was assigned to the research area Trustworthy Multiparty Interactions in Dynamic Networking Environments.

Background

Prior to my post.doc. position, I spent a few years as a research scientist in computer security at Telenor Research and Development. I took leave for four years to carry out my doctoral studies at the Department of Telematics, NTNU before returning for a one-and-a-half year stint at Telenor Research and Development. My doctoral studies resulted in a dissertation titled Encrypted Computation. In parallel with these studies I held introductory courses in computer security at two universities in addition to a regional university.

Main Research Interests

• Anonymization and pseudonymization (primary focus has currently detoured into this).
• Stochastic models and risk theory (former focus).
• Mobile agents and security (the initial focus of my doctoral work).
• Fault-tolerance and security.
