Cryptography Stack Exchange is a question and answer site for software developers, mathematicians and others interested in cryptography. It's 100% free, no registration required.

I would be starting groundwork for my thesis in cryptography , I would like to know what are current open problems in cryptography, few I know of are

  1. Fully Homomorphic Encryption
  2. Functional Encryption ( which is bigger framework for solving the below)
    2.a Identity Based Encryption
    2.b Attribute Based Encryption
    2.c Predicate Based Encryption
  3. Searchable Encryption ( It can be treated as Functional Encryption , but there is huge literature on this which is not directly fitting in the framework of FE )
  4. Private Information Retrieval
  5. Provable Security

Can others please let me know of other areas ?

Hello, welcome to crypto :) Unfortunately SE doesn't do very well with these kind of questions - for a brief rationale of why, see our faq - we discourage question where there is no actual problem as we've found over time they just don't work. As such I'm closing this. However, if you did have a specific problem in mind and I'm just missing it, do feel free to edit & use the flag link or reply here and it can be re-opened. –  Ninefingers Mar 3 '12 at 10:08
Also, if you have any questions I'm usually around in chat. –  Ninefingers Mar 3 '12 at 10:09

for a non-trivial problem, based on an efficiently falsifiable assumption?"
