Lightweight Homomorphic Encryption Algorithm for Secure Cloud Storage in Bibliographic Control Systems

Abstract

Empirical research conducted over the past few years suggests that the rapid expansion of digital bibliographic data in cloud-based library management and data retrieval systems has heightened concerns regarding confidentiality and privacy. Classical methods of encryption protect stored data, but they do not permit efficient access to encrypted data. This lack of functionality makes the system nearly unusable. This study develops a homomorphic encryption technique for safe bibliographic cloud storage and retrieval in order to address these problems. In order to accomplish security and access control goals without sacrificing the effectiveness of cataloging and retrieval systems, partially homomorphic encryption is utilized. It is more secure than both encrypted and unencrypted systems. When forced to employ completely homomorphic techniques, libraries and other archive systems frequently experience significant computational delays, which makes the systems slow. For bibliographic databases with high query traffic, systems that use the suggested LHE framework scale with nominal computing cost, have low latency, and have minimal ciphertext overhead—the ideal setup for systems that need to respond quickly. The algorithm's effectiveness is confirmed by its ability to survive numerous known cryptographic assaults while exceeding traditional systems in terms of encryption speed, storage efficiency, and query response time. By strengthening secure cataloging, controlled access, and privacy-centered search operations, LHE enhances bibliographic control systems and is beneficial for academic cloud infrastructures and next-generation digital libraries. This research augments the domains of cloud security and library and information science by offering innovative strategies for the secure management of bibliographic data.
