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
- Fully Homomorphic Encryption
- 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
- 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 )
- Private Information Retrieval
- Provable Security
Can others please let me know of other areas ?
