Abstract:

Cloud services must be dealt with in a way that preserves the privacy of customer's data. In order to achieve this, homomorphic encryption is used which helps to complete business within the cloud environment while preserving the privacy of data from viewing it. In this article, we use the Brakerski-Fan-Vercauteren (BFV) algorithm, which requires high and expensive calculations, using the Hybrid-Position-Residues (HPR) number system to reduce the cost of calculations while maintaining the efficiency of the algorithm.
