: Cloud storage has now become widely used for the management of sensitive documents, thereby casting a huge shadow over the user’s right to privacy and the security of his data. One of the earliest encryption methods is AES, which is the most widely used among the rest of the traditional methods, and it still provides confidentiality only but not secure searching over the encrypted data. The new research introduces a QKD + AES-based Symmetric Searchable Encryption (SSE) system applicable to dynamic datasets and thus allowing secure keyword-based search without compromising the privacy. Under this scheme, QKD is the method used to send the AES encryption keys to the client and server securely, and thus the quantum adversaries cannot either intercept or manipulate the keys. After that, the AES encryption holds the data securely, while the SHA-256 hashing for the indexing of keywords is employed which allows an efficient and secure search over the encrypted data to be done. The system, besides giving forward privacy which forbids the connection of new data to previous searches, also provides backward privacy which assures that deleted entries will not be accessible in future queries.
