Dynamic Searchable Symmetric Encryption (DSSE) is a prospective technique in the field of cloud storage for secure search over encrypted data. A DSSE client can issue update queries to an honest-but-curious server for adding or deleting his ciphertexts to or from the server and delegate keyword search over those ciphertexts to the server. Numerous investigations focus on achieving strong security, like  forward-and-Type-I - -backward  security, to reduce the information leakage of DSSE to the server as much as possible. However, the existing DSSE with such strong security cannot keep search correctness and stable security (or  robustness , in short) if irrational queries are issued by the client, like duplicate add or delete queries and the delete queries for removing non-existed entries, to the server unintentionally. Hence, this work proposes two new DSSE schemes, named SR-DSSE a  and SR-DSSE b , respectively. Both two schemes achieve  forward-and-Type-I - -backward  security while keeping  robustness  when irrational queries are issued. In terms of performance, SR-DSSE a  has more efficient communication costs and roundtrips than SR-DSSE b . In contrast, SR-DSSE b  has a more efficient search performance than SR-DSSE a . Its search performance is close to the existing DSSE scheme with the same security but fails to achieve  robustness .
