Welcome!



My name is Kim Nguyen,
I am a number theorist working in cryptography.

(At my thesis defense, 18th of December 2001).

Short resume:

In December 2001 I defended my Ph.D. thesis (successfully).

2004-:
In January 2004 I joined the
Bundesdruckerei (the German federal print) that is located in Berlin.
Here I work on the cryptographic and interoperable features of the new Machine Readable Traveldocuments
that are equipped with a contactless high security controller to store biometric data.
It is especially worth noticing that the German passport will make use of elliptic curves!
I currently live and work in Berlin.

2001-2003:
In July 2001 I joined the Crypto Competence Center of
Business Unit Identification, Philips Semiconductors.
I am currently working and living in Hamburg, Germany.

1998-2001:
Ph.D. student at the Institute for Experimental Mathematics,
University of Essen, Germany.
Supervisor: Prof. Dr. Dr. h.c. Gerhard Frey.

1998:
Staatsexamen in mathematics, physics, University of Göttingen, Germany.

1997:
Diploma in mathematics, University of Göttingen, Germany.

Research interests:
Number theoretical cryptography,
especially elliptic and hyperelliptic curves,
finite fields

My thesis deals with the interpretation of discrete logarithm problems in the
(cohomological) language of Brauer groups.
