Web• GSW FHE Scheme The GSW FHE scheme is presented most simply in terms of the gadget-based trapdoor described in [1, 3, 5, 34, 39]. The heart of GSW scheme are the following additive and multiplicative homomorphisms for tags and trapdoors. Let A 2Zn m q be LWE samples with secret key s2Zn 1 q, and for i= 1;2, let A i= x iG AR i; where x i2Z

GSW is based on approximate eigenvectors of matrices. The ciphertexts in GSW are square matrices, and homomorphic additions and multiplications are just matrix additions and multiplications, respectively. tonja norman gastonia ncWebJul 2, 2024 · Recall that in GSW-FHE, a ciphertext of a bit is a matrix such that tC = eR + μtG for a secret key vector t and small noise vector e. 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. tonjarene bronston
