The Magic of Lattice and The Eye of a Falcon

--

To understand lattice cryptography, you need to understand polynomials, as our bit values are converted into polynomials. Our operations are then conducted with polynomial multiplies and add, and taken with a (mod p) operation (and where p will be the maximum value we generate for the polynomial values). For example, to multiply (5x²+1) and (2x+3), we get:
