Abstract:

Since 96 a new public key cryptosystem called NTRU has been developed by
three mathematicians of Brown university:  Hoffstein, Pipher, Silverman.
Its security is based on special instances of lattice problems. We review
the encryption and signature scheme and sketch a polynomial
generalization.

Biography:

Patrick Sole received the Ingenieur and the Docteur Ingenieur degrees from
Ecole Nationale Superieure des Telecommunications, Paris, France in 1984
and 1987, respectively, and the Habilitation a Diriger des Recherches
degree from Universite de Nice, Sophia-Antipolis, France, in 1993.

He has held visiting positions at Syracuse University, Syracuse, NY,
during 1987-1989, Macquarie University, Sydney, Australia, during
1994-1996, and at Universite des Sciences et Techniques de Lille, Lille,
France, during 1999-2000. He has been a permanent member of Centre
National de la Recherche Scientifique since 1989, and with the rank of
Directeur de Recherche since 1996. His research interests include coding
theory (covering radius, codes over rings, geometric codes),
interconnection networks (graph spectra expanders), and vector
quantization (lattices, theta and nu series).
