The entries only have 128 bits, compared to what we started with which was 134 bits. fob footballNow that we know what lattice to use, let’s see how to decrypt the ciphertext. Our ciphertext is e ≡ rh + m (mod q). Make a new row vector (0 N, e) by prepending N 0’s to the coefficients of e. This is in the same dimensional space as our lattice, but it’s not necessarily a lattice point. fob flintlockWebIntuitively, if we have a problem (1) in some lattice space we can reduce it to a hard problem (2) in another related lattice space.
