Outsourcing data to cloud providers is becoming more and more common. While this offers great advantages in terms of maintenance cost, the confidentiality of the data is in peril. One solution to this problem is the use of encryption. While standard symmetric encryption algorithms like e.g. AES offer good security by encrypting all records, the cloud data store loses any search functionality and degrades to just a bunch of encrypted files. However, among the desirable functionality of a data store is the ability to efficiently perform full-text search, sorting or calculations.
By allowing a small information leakage to the server, advanced encryption schemes allow to efficiently search, sort or compute on encrypted data. In this seminar, we will look into the key properties of some encryption schemes and discuss the trade-offs of proposed schemes.
