Challenge "Lightweight Introduction to Lattices — Part 1"  

  By: admin on May 16, 2020, 4:03 p.m.

Lattice-based cryptography schemes are relevant for current post-quantum cryptography research. This challenge series accompanies the basic theory from a chapter of the CrypTool Book called "LIGHTWEIGHT INTRODUCTION TO LATTICES". In this part of the challenge series we introduce systems of linear equations to find a hidden message in a picture.

Maybe it's not too much of a hint to reveal that the 7-letter string is a meaningful english word. I first struggled as the asccii interpretation doesn't seem to be unique.

There are, by my count, 8 different symbols in the picture. I'm able to find a digit value for each of them satisfying the equilibrium condition on each vertex. So far, so good.

But how do you arrive at 7 ASCII values from this?? Any hint appreciated...
