We note that all the examples so far can use secret-key homomorphic encryption. However, as we will see later in Section 2.2.6, for homomorphic encryption the distinction between public-key and secret-key encryption is immaterial. Zero-knowledge. Homomorphic encryption can also be used in a very simple zero-knowledge proof

Data encrypted with homomorphic encryption is many times larger than unencrypted data, so it may not make sense to encrypt entire large databases, for example, with this technology. Instead, scenarios where strict privacy requirements prohibit unencrypted cloud computation, but the computations themselves are fairly lightweight, are meaningful use cases.

Homomorphic encryption is the conversion of data into ciphertext that can be analyzed and worked with as if it were still in its original form.

What Is Encryption?

A homomorphic cryptosystem is like other forms of public encryption in that it uses a public key to encrypt data and allows only the individual ...
