In recent days most of the industrial firms have been searching for ways to keep their data as secured and protected as possible. They have indulged in research works to find a mechanism that can be simple, convenient and guarantees high level security to large amount of data that is being manipulated every now and then. Among such mechanisms, one mechanism that satisfies all these requirements is Homomorphic Encryption (HE). Homomorphic Encryption schemes facilitate computation on the encrypted data, yielding different output every time is considered as an edge over traditional encryption algorithms. HE schemes ensures integrity and security of data, against threats and violations. Researchers expanded the dimensionality of the homomorphic encryption to another level through Carmichael’s Theorem-Based Homomorphic Encryption (CTHE) scheme and Modified Enhanced Homomorphic Encryption (MEHE) scheme. CTHE and MEHE schemes are reviewed in this article to show its robustness against invasive attacks.
