At the core of lattice-based cryptography are issues that are believed to be onerous for both classical and quantum computer systems to unravel. One such downside is discovering the shortest vector in a high-dimensional lattice, a problem that turns into exponentially harder as the scale increase. The beauty of those lattice issues lies in their…

Homophonic substitution was now used not just for single letters but for frequent two- or three-letter mixtures. Just like some other plaintext, Alberti really helpful enciphering these code words with his polyalphabetic cipher as well. This was the first European instance of superencipherment (I’ll tell you more about that in the next sections). Hash capabilities…
