The scientific field of cryptography has been developing very rapidely in recent years. There is a growing number of conferences in cryptography in addition to the annual Crypto and Eurocrypt meetings. However. most of these meetings have a broad focus, and at Crypto and Eurocrypt, in particular, the audience is becoming less scientific as applications of cryptography increase, and as the number of attendees who are not experts increases.

This seminar has given an opportunity for key cryptologists to meet, to interact, to focus on the scientific foundation of cryptography, to identify the current central problems and to work on them. Enough time has been left during the seminar for informal interactions.

The lectures presented at the seminar have covered main directions of current cryptology, emphasizing those areas that are most amenable to mathematical reasoning. Talks have been given on

  • new encyrption and signature schemes,
  • security of cryptosystems and practical attacks,
  • cryptographic aspects in communication networks,
  • interactive proof systems,
  • secret sharing,
  • cryptography and number theory,
  • stream and block ciphers

Additionally, some lectures have covered important issues of general interest like key escrow and copyright aspects.

This seminar has continued the tradition of a series of previous workshops at the Centre International des Recherches Mathematiques, Luminy France, the Mathematische Forschungsinstitut Oberwolfach and the IBFI Schloss Dagstuhl (Dagstuhl-Seminar 9339 27. Sept-01 Oct. 93).
