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.

New Book on
Multiparty Computation
With Ronald Cramer and Jesper Buus Nielsen, I have just published a new
book on
Information Theoretically Secure Multiparty Computation and Secret
Sharing.
The book is published by Cambrigde University Press. Get it here.
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 4 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.
IntsåRing
A duo with
Pia Nygaard. We play nordic folk, insturmentels and songs, on fiddles,
mandolin and guitar.
The home page has more info,
pictures and sound clips.
Ostinat Expressen
Originally a 4-piece band with
fiddle/guitar,
clarinet, accordion and double bass. After a long break, the
band was revived in 2013, now including a percussionist. On our Soundcloud page,
you can hear some
new demo material. The old version of the band released one CD, “Waltz for a
Princess”.
Some clips from that CD:
Listeren, schottish by Julie Heebøll
Waltz for a princess, by Julie Heebøll
Madam Blå, hopsa by Ivan Damgård
Baldrian
A 4-piece band with fiddle, accordion,
double bass, guitar, mandolin etc. and vocals. Not active anymore.
Traditional
and not so traditional folk for dancing,
concerts and
parties. We released one CD “Zinklar”.
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)
