One Digit Checksum for Data Integrity Verification of Cloud-executed Homomorphic Encryption Operations
Abstract
Homomorphic Encryption~(HE) is used in many fields including information storage, data protection, privacy preservation, blockchain, and authentication. HE allows an untrusted third party to perform algebraic operations on encrypted data. Protecting the results of HE against accidental or malicious tampering attacks is still an open research challenge. In this paper, we introduce a lightweight technique that allows a data owner to verify the integrity of HE results performed in the cloud. The proposed method is quick, simple, and applicable, as it depends on adding a single digit to the encrypted message before storing it in the cloud. This digit represents verification proof and it is later used to ensure a verifiable HE. Our technique can be integrated with any HE scheme that uses encryption with non-isolated plaintext.
