Dynamic Searchable Symmetric Encryption (DSSE) provides a simple and fast storage as well as retrieval method for encrypted profiles which stored in cloud. However, due to the nature of the symmetric encryption algorithm, it allows only one client to access the data. To make the scheme more practical, this paper propose a multi client dynamic symmetric searchable encryption scheme that could allow multi-client to search the privacy data with the delegation search token and dynamic delete expected files with delete token. Compared with similar works, our construction achieves a balance in network security and practical performance. We also demonstrate that the proposed scheme has same IND-CKA2 security property against adaptive adversary.
