I am a professor at the
computer science department of Aarhus University. Below, you will find links,
most of which are
related to my main research
interests: cryptography, data security, discrete math, quantum information,
algorithms and complexity.
Finally there are links
connected to my main interest aside from work: music, and folk music in
particular.

The Provable Security Controversy
In 2006-2007, a controversy started about what proofs and security reductions
in
cryptography actually mean and whether they are useful, a debate initiated
(among others) by
Koblitz and Menezes. Unfortunately, a lot of this important debate has been
obscured by
misunderstandings and misconceptions. In the hope of helping to clarify some of
these issues,
I post here my position paper on the subject, A "Proof-Reading" of
Some Issues in
Cryptography, which appeared in ICALP 2007.
The version here is a slightly updated version of what appears in the
proceedings.

Courses
At the computer science department, I teach
the following courses:
- The Introductory Cryptography course that runs in the fall (1.+2 .quater); and
- The Cryptologic Protocol Theory course that runs in the spring (3.+4. quater)
- The Course in Quantum Information Processing that runs in the fall (1.+2 .quater)
- The dSik course, an introductory course in IT security (in Danish) that runs in the spring (4. quater)
Projects, etc.
I am currently involved with the following
major research projects:
- CACE Computer Aided Cryptography Engineering
- CFEM Center for research in the Foundations of Electronic Markets
- ITSCI IT security for Citizens, see also the common site of this and two related projects.
In day-to-day work, I am head of the Cryptography Group of the computer science department
Business
I am a co-founder and owner of Cryptomathic, a local software and
consulting company in data security and cryptography
I am also a co-founder of
Partisia, a company doing market design
and implementation, based on secure multiparty
computation.
Music
I play primarily fiddle and guitar, mostly
Danish and Nordic folk music. I am or have been involved in 3 bands:
Jydsk på Næsen
A 4-piece traditionally
oriented band with 2 fiddles, accordion and double bass. Instrumental
traditional and
self-composed music for
dancing and concerts. We released 1 LP, 4 CD’s
and several tapes and celebrated our
30 year anniversary in
2009. The home page has more info, pictures
and sound clips.
Baldrian
A 4-piece band with
fiddle, accordion, double bass, guitar, mandolin etc. and vocals.
Traditional and not so

Some clips from a live
recording:
Reels in A (traditional
Danish tunes)
Øster og Vester (“East
and West”, traditional Danish song)
Brudestykker (Traditional
Bridal dances from the island of Fanø)
Ostinat Expressen
A 4-piece band with
fiddle/guitar, clarinet, accordion and double bass. Not active anymore.
