Project title: Security of Homomorphic Encryption
Project description: My Ph.D. project will focus on homomorphic encryption, that is: encryption which allows for evaluation encrypted data without decrypting it first. The project will look into security notions on this type on encryption. I will also investigate whether or not an IND-CCA-1 homomorphic encryption scheme is theoretically possible, which is an open question in the field. It is important to have meaningful security notions on any type of encryption, so as to judge the security and also compare schemes. Due to the property of evaluating encrypted data, not all current security notions are achievable for a homomorphic encryption scheme (e.g. IND-CCA-2), and it is therefore worth looking into whether or not a new set of security notions should be constructed for this type of scheme, and also what these notions should contain.
