Dynamic Searchable Symmetric Encryption (DSSE) allows a client not only to search over ciphertexts as the traditional search- able symmetric encryption does, but also to update these ciphertexts according to requirements, e.g., adding or deleting some ciphertexts. It has been recognized as a fundamental and promising method to build secure cloud storage.
