Packing Messages and Optimizing Bootstrapping in GSW-FHE

WebFirstly, they noticed that the conventional GSW-FHE uses only one “slot” to place a message bit. To achieve an optimal compression rate, more message “slots” must be utilized. Their solution is to use LWE with matrix secrets, which … WebThen the latter works about the GSW-FHE are mainly RLWE-based schemes, including Ducas and Micciancio’s scheme FHEW [18] and Chillotti et al.’s scheme TFHE [13,14].

For the plaintext space with a random matrix M⁠, they would like that TC = E + MTG for the secret key T⁠. Hence, there should be a matrix Y such that TY = MT when the ciphertext of matrix M is C = BR + YG⁠.
