Cryptography

Summary

The First Dagstuhl Seminar on Cryptography was organized by Andrew M. Odlyzko (Murray Hill), Claus P. Schnorr(Frankfurt)and Adi Shamir (Tel Aviv). The 38 participants came from 12 countries. Unfortunately Andrew Odlyzko fell ill shortly before the meeting and could not attend.

The 31 lectures covered a broad range of actual research in cryptography dealing with new cryptographic systems and their cryptanalysis. New schemes have been presented for public key signatures,key distribution,key sharing,authentication and cryptographic hashing. Some talks were given about various aspects of number theory like lattice reduction and factorization. Other talks studied cryptographic problems in the framework of coding and information theory. Adi Shamir proposed in an off-schedule discussion an encryption scheme for pictures. It later on has been visualized on some nice slides by Antoine Joux.
