Abstract

See full text

Embodiments are described for a method of performing fully homomorphic encryption on a data set by providing a multivariate encryption polynomial to produce an encrypted data set and a multivariate decryption polynomial to decrypt the encrypted data set, providing a multivariate function polynomial that represents an operation to be performed on the encrypted data set, and recomposing the function polynomial with encryption polynomial. Also described are a method comprising providing a private key comprising a multivariate polynomial polynomial function to encrypt plaintext data to produce ciphertext, and providing a public key comprising a multivariate set of equations derived from the private key and a randomly selected injective vectorial multivariate function to decrypt the ciphertext.
