Title: Security Notions of Cryptography, History and Progress
The formal study on the security notions of cryptography started in 1980's.
A typical example is the security formulation of public-key cryptography.
The simulation-based formulation (paradigm) was established through the
security formulation
of cryptographic protocols, and the most advanced one on the paradigm is
the universal composablity (UC).
In this talk, I will survey the history and progress of these security
notions of
cryptography.
