Abstract: Large volumes of electronic data have been created in recent years, and enterprises that require data recovery services may be affected by a variety of natural or man-made disasters, resulting in massive data losses. Encryption is the most reliable solutions for enhancing security and privacy. Any security vulnerabilities have been uncovered, such as data loss while data is stored in cloud storage. To safeguard data transactions in the public cloud, this study presents a layered encryption approach. In the suggested method paradigm, asymmetric and symmetric cryptography are mixed. Encryption primitives such as multi-client functional encryption (MCFE) enable an evaluator without needing to obtain each client's plaintext set to discover the intersection of all sets. An extensible variant of the MCFE techniques for set intersection is presented in this study. According to our analysis, this relaxation is required for the practical application of secure multi-client set intersections.
