Abstract
Some embodiments are directed to a cryptographic method for homomorphic computation. The method works on multiple messages encrypted in a single packed GLWE or GLWR ciphertext. The packed GLWE or GLWR ciphertext comprises a mask and a body. Each value in the body is associated with a different secret key and corresponds to a message in the multiple messages. Various homomorphic operation can be performed on the packed GLWE or GLWR ciphertext.
