Quantum-Based QKD and Sugar-Salt Encryption Approach in Cloud-Fog Computing to Strengthen Protection of Online Banking Data

Cloud computing is swiftly developing, delivering a diverse spectrum of computing utilities like databases, storage, and servers. It transfigures the way data storage is done and securely circulated among numerous users. Nevertheless, enabling privacy and restricting identity breaches when availing cloud utilities is essential. Fog Computing, an updated version of the cloud framework, utilizes a decentralized architecture to maintain data between the cloud and the data sources. This procedure seeks to improve performance, network connectivity, and most importantly provide security. Quantum key distribution (QKD) is employed in fog computing architectures to develop and circulate keys. The employed keys change their quantum configurations, enabling them to be highly safe. Further, an intermediary maintaining the key can identify any endeavor by illegal entities to operate it. In this research article, we utilize sugar-salt encryption, an approach designed to oppose brute-force invasions efficiently. This encryption procedure delivers erroneous data in reply to wrong password/key insertions, improving data protection, which is pivotal in online based banking data protection.
