10 Facts About Homomorphic encryption

Homomorphic encryption is a form of encryption that permits users to perform computations on its encrypted data without first decrypting it.

Homomorphic encryption can be used for privacy-preserving outsourced storage and computation.

Sensitive data, such as health care information, homomorphic encryption can be used to enable new services by removing privacy barriers inhibiting data sharing or increase security to existing services.

Homomorphic encryption is a form of encryption with an additional evaluation capability for computing over encrypted data without access to the secret key.

Homomorphic encryption can be viewed as an extension of public-key cryptography.

Homomorphic encryption includes multiple types of encryption schemes that can perform different classes of computations over encrypted data.

Some common types of homomorphic encryption are partially homomorphic, somewhat homomorphic, leveled fully homomorphic, and fully homomorphic encryption:.

In terms of malleability, homomorphic encryption schemes have weaker security properties than non-homomorphic schemes.

Specifically, fully homomorphic encryption schemes are often grouped into generations corresponding to the underlying approach.

Problem of constructing a fully homomorphic encryption scheme was first proposed in 1978, within a year of publishing of the RSA scheme.
