Homomorphic encryption (HE) enables processing encrypted data without decrypting it. This technology can be used, for example, to allow a public cloud to operate on secret data without the cloud learning anything about the data. Simply encrypt the secret data with homomorphic encryption before sending it to the cloud, have the cloud process the encrypted data and return the encrypted result, and finally decrypt the encrypted result. Here is a simplistic "hello world" example using homomorphic encryption.
