*Working at the Center for Communications Research - Princeton*

### Our Mission

The Center for Communications Research in Princeton
performs applied mathematical and computational research in cryptology and
related disciplines.
### Mathematics

CCR-P conducts mathematical research supporting the twin
tasks facing cryptologists: cryptography and cryptanalysis. Mathematics remains
the fundamental science used to create and analyze the complex algorithms used
to encipher vulnerable communications. Virtually every branch of pure and
applied mathematics has proved to be useful in these efforts. For example,
techniques from the geometry of algebraic curves provide better methods for
detecting and correcting errors in data transmission. Even where no explicit
mathematics is involved, the mathematical mode of thinking seems to be ideally
suited to cryptologic problems.

### Speech and Signals

As the modes and means of modern communications
become more complex, we have expanded our research into other areas including
speech, the processing of signals to remove noise and distortion, and network
security.

### Summer Program in Mathematical Cryptology

Each summer, CCR-P runs an
intensive ten-week summer conference on applied mathematical problems (SCAMP).
The conference concentrates on a problem area in cryptology. Some 20-25 academic
mathematicians are invited to join with our research staff for these
conferences.
The visitors are a very strong group of research mathematicians ranging in
age from undergraduates to emeritus professors. In recent years, we have made a
particular effort to include some undergraduate and/or graduate students who
have demonstrated outstanding talent.

Typically, we have a mix of new and returning participants, depending upon
individual proclivity for and interest in the particular problem set. Those
having an outstanding talent for our problems may also be invited to join our
permanent research staff.

The format of the program is rather relaxed. The first two weeks are spent
attending lectures where the problems are described, the remaining eight weeks
permanent research and program participants spend working on whatever problem,
or piece thereof, is of interest to them. Joint work is encouraged and informal
bull sessions or lectures are used to present partial results or even half baked
ideas which often stimulate better ideas.

Cryptology, as a field of applied mathematics, is remarkable for the range of
abstract mathematics which finds striking application. As might be expected,
algebra, number theory, combinatorics and statistics play a major role, but
topology, algebraic geometry and harmonic analysis have been the source of
unexpected and critical contributions. One has an extraordinary opportunity to
see an abstract theory turned into an effective tool solving real problems. On
the one hand, this provides a deep understanding of the theory and its
ramifications; and on the other, provides the exhilaration of solving problems
of immediate and substantial importance.

### Requirements for employment

In addition to U.S. citizenship, a high
level of security clearance is required for our work. IDA CCR-P is an equal
opportunity employer.
