SUMMARY:Crypto Reading Group - Mohammad Hajiabadi-Challenges in Realizing C
 CA\nin Advanced Encryption Schemes
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n\n Mohammad Hajiabadi\n\nAFFILIATION:\n University of
  Waterloo\n\nLOCATION:\n MC 6029\n\nABSTRACT:CCA security is a fundamental
  notion in cryptography. There\nare standard techniques to generically ach
 ieve CCA security for\nall-or-nothing type public-key encryption schemes\,
  such as heuristic\napproaches based on Fujisaki–Okamoto\, or constructi
 ons in the\nstandard model using tools like hinting PRGs. However\, in mor
 e\nadvanced settings\, such as functional encryption or threshold\nencrypt
 ion\, these generic approaches break down. Moreover\, defining\nCCA securi
 ty in these settings is itself non-trivial and leads to\nsubtle definition
 al challenges.\n\nIn this talk\, I will discuss these issues\, highlight t
 he key\nobstacles\, and present several open problems\, along with possibl
 e\ndirections for addressing them.
