  • Homomorphic Encryption Case Study

    1076 Words  | 5 Pages

    The so-called fully homomorphic encryption is considered the Holy Grail of Cryptography. Addition and multiplication are the main building blocks of computers, and the ability to make calculations on encrypted data without decrypting it, would lead to a whole new level of security.

    the receiver. It is used in digital signatures the hash is encrypted using sender’s private key and then encrypted using public key and sent to the receiver and the receiver decrypts the message using the private key. It is used in password storage A good system does not store the plaintext equivalent but store something else which include some randomness .so now if we use hash and because of its onewayness it is impossible to get back the password. If we use pure hash in the password and encrypt
