CryptDB Mechanism on Graph Databases
Nahla Aburawi · University of Liverpool
The work presented in this thesis is concerned with the database security aspects. In particular, we address the problem of querying encrypted data in graph databases. The thesis considers the most popular databases security methods from the literature: (i) multi-layered encryption and (ii) encryption adjustment. The encryption is one of the effective ways to protect sensitive data in a database from various attacks. Querying encrypted data includes two challenges. Either the data should be decrypted before the querying, leaving it vulnerable to server-side attacks, or one has to apply computationally expensive methods for querying encrypted data.
