PUBLIC KEY ENCRYPTION SCHEME BASED ON KEYWORD SEARCH

Abstract

This study explores the concept of a Public Key Encryption Scheme (PKES) with an emphasis on enabling keyword search functionality. The aim of this research is to develop a cryptographic framework that allows users to securely search over encrypted data without revealing sensitive information. The study investigates various methods and techniques employed in PKES to achieve efficient and privacy-preserving keyword search capabilities. The research highlights the increasing importance of data privacy and the need for secure information retrieval over encrypted data. Traditional encryption methods hinder search functionality, making it challenging to perform keyword searches on encrypted data. To address this limitation, the study focuses on PKES, which facilitates search operations while preserving the confidentiality of the underlying data. Experimental research design was used for this research. To accomplish the objectives, the study employs a combination of cryptographic algorithms and data transformation techniques. Public key encryption algorithms are utilized to secure the data, ensuring that only authorized users can access the information. Additionally, searchable encryption methods, such as Searchable Symmetric Encryption (SSE) and Index-Based Encryption (IBE), are explored to enable efficient and secure keyword searches on encrypted data. The results of the research demonstrate the feasibility and effectiveness of the proposed PKES with keyword search. The developed framework allows users to encrypt their data and store it securely, while still being able to search for specific keywords without decrypting the data. The experiments conducted on different datasets showcase the efficiency of the implemented techniques, providing a practical solution for secure data retrieval. In conclusion, the study presents a robust and privacy-preserving Public Key Encryption Scheme that incorporates keyword search capabilities. The research contributes to the field of cryptography by addressing the limitations of traditional encryption methods and offering an effective solution for secure information retrieval. The findings highlight the significance of PKES in safeguarding sensitive data while allowing users to perform keyword searches conveniently
