Explaining Post-Quantum Cryptography with Cartoons
summary
Introduces lattice-based post-quantum encryption (illustrated by a snail moving on a 2D lattice as an intuitive metaphor for high-dimensional lattices used in practice) and hash-based signature schemes (explained as digitally signing statements stored in combination-lock boxes). Mentions other families such as code-based and isogeny-based systems briefly, and focuses on accessible, cartoon-based visual explanations rather than mathematical rigor, aimed at IT security professionals and instructors.
