WebThe LLL algorithm is a lattice reduction algorithm, meaning it takes in a basis for some lattice and hopefully returns another basis for the same lattice with shorter basis vectors. … Now 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.
