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. – Antony Vennard Mar 3 '12 at 10:08
Also, if you have any questions I'm usually around in chat. – Antony Vennard Mar 3 '12 at 10:09

As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or specific expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, see the FAQ for guidance.

"Is it possible to obtain a three round zero knowledge protocol with negligible soundness error
for a non-trivial problem, based on an efficiently falsifiable assumption?"
