Abstract: Data processing methods allowing to query encrypted data, such as CryptDB (Popa et al., 2011a) utilize multi-layered encryption and encryption adjustment in order to provide a reasonable trade-off between data security protection and data processing efficiency. In this paper, we consider querying of encrypted graph databases and propose a novel traversal-aware encryption adjustment scheme which trades efficiency for security. We show that by dynamically adjusting encryption layers as query execution progresses, we can correctly execute the query on the encrypted graph store revealing less information to the adversary than in the case of static adjustment done prior to execution.
