CS647 Advanced Cryptography
Cryptography has evolved significantly since the
introduction of one-way functions for public-key cryptography and digital
signatures in the 1970's. A number of new interests were born from
relations between cryptography and complexity theory: interactive proofs,
zero-knowledge protocols, multi-party computing, etc.
Another great change in the world of cryptography is currently
unveiling itself: the impact of quantum computing/information processing
on cryptography. On one hand, quantum computing promises new cryptanalitic
tools on existing one-way functions (Shor's algorithms), but on the other
hand, quantum cryptography promises perfect key distribution.
Our purpose is to bring the student to understanding of the
current issues in the fast evolving world of cryptography.
