I am a full professor at NTNU since 2002. My PhD degree in 1990 on cryptographic protocols. I spent my sabbatical year at UCSB in 2013 visiting Dick Kemmerer’s computer security group.
My main fields of interests are in the technology of information security, data communication and networks. My long-term research aim is to understand how to define and construct provably sound cryptographic protocols, and to understand their potentiality as information security mechanisms in networked systems, with applications to society at large. Cryptographic Protocols can be considered as distributed algorithms that employ cryptographic primitives for securing distributed computerized communication systems. Their computational multiparty goals are to restrict, establish and preserve information (i.e. security properties) robust against intentional modifications to the protocol algorithms. Digital Tracks are pieces of digital information that can be attributed to
individuals.I have done research on privacy-preserving protocols, such as digital cash and e-health transactions; currently this activity is targeted on the e-voting problem. Conversely, I want to understand the properties of digital tracks as technical evidence in after-the-fact investigations in networked systems, the emerging field of digital forensic science.
The start now will be Haakon and I constructing and analysing schemes for public key distribution in the NDN environment, employing a motivating IoT application scenario, and based on the Chronosync functionality.
