Homomorphic encryptionallows computations to be performed directly on encrypted data without decrypting it first. This technology is particularly useful for securely transmitting confidential data to a cloud service provider (CSP) and allowing the CSP to process the data without having any visibility into its content. This maintains data confidentiality even during processing. It is not about securing data at rest and in transit or simply storing data across nodes.
