Index Based Searchable Encryption on Cloud Data Using Asymmetric Encryption Algorithm

Abstract

Index-based searchable encryption (SE) techniques allow users to securely search over encrypted data without revealing sensitive information to the cloud server. However, existing SE schemes often suffer from efficiency and security trade-offs. We propose a novel approach for index-based searchable encryption on cloud data using an asymmetric encryption algorithm. With the increasing adoption of cloud storage services, ensuring the privacy and security of data stored in the cloud has become a serious concern. Proposes a novel approach for keyword search on encrypted data in cloud storage using an Elliptic Curve Cryptography (ECC) encryption approach. It utilizes index structures to enable efficient keyword search operations on the encrypted data. A secure index is generated during the encryption process, which allows for efficient retrieval of encrypted data related to specific keywords. Furthermore, our scheme introduces an indexing mechanism that preserves the confidentiality of the search queries while enabling efficient search operations. Only authorized users possess the necessary decryption keys to retrieve the plaintext information.
