In 2009 Craig Gentry proved that Fully Homomorphic Encryption can be applied and realized in principle. Homomorphism allowed us to perform arbitrary computations and calculations on encrypted data. With RSA being the first cryptosystem to hold homomorphic properties, there came other additive and multiplicative cryptosystems. However, fully Homomorphic encryption proved to be the ultimate cryptographic solution to ensure security of data on cloud. It enables processing and computing arbitrary functions over the encrypted data thereby reducing the probability of accessing the plain text.
