Summary:
Searchable encryption, which has been gradually used in practice, gives search feasibility on encrypted database stored on a server. However, once the search is done, state of probabilistic encryption is sometimes transited to state of deterministic encryption. In this paper, we evaluate the relation between encryption state and search process on a searchable encrypted database from a viewpoint of information entropy.
