This paper introduces an authentic framework that relies on verifiable searchable encryption security and a mechanism for managing resource limitations on the client-side. The framework is specifically designed to tackle the difficulty of achieving a high level of data security while minimizing the storage requirements on the client-side. The framework combines a symmetric key encryption technique with a Searchable Encryption Index (SEI) to allow for efficient searches while maintaining data secrecy. One important aspect is the utilization of cryptographic verification tokens, which enable clients to verify the integrity and validity of search results while keeping a consistently small storage space requirement. This is accomplished by exclusively storing crucial keys and tokens on the client's end. Our framework incorporates advanced security measures such as key rotation, auditing systems, and end-to-end encryption. This ensures a strong and efficient solution for safe data searches, making it especially suitable for contexts with limited client-side resources. The practical usefulness of searchable encryption is validated through rigorous testing and third-party audits, ensuring a balance between security, efficiency, and scalability.
