Homomorphic EncryptionHomomorphic encryption supports mathematical operations on encrypted values. Partial Homomorphic Encryption (PHE) supports a few arithmatic operations, while Full Homomorphic Encryption (FHE) supports add, subtract, multiply, and divide. Homomorphic encryption normally involves a public key to encrypt the data, and a private key to decrypt it. There have been four main generations of homomorphic encryption, and the most recent being the HEAAN method.
