Abstract

The famous scheme of Van Dijk, Gentry, Halevi and Vaikuntanathan (DGHV) style of Fully Homomorphic Encryption (FHE) is simple to implement. This paper proposes how this scheme can be modified and used for double encryption to secure files stored at third party like Cloud service provider (CSP). The files belong to an incremental text model which is followed by majority of confidential documents. Encryption is similar to a homomorphic hash function. A protocol is also proposed to detect if files have been tampered, and the tampering can be located up to single file level or up to a word of file level.
