📄️ Backpack Cryptography
I love this cryptosystem so much, I carry it everywhere in my backpack. To lighten the load, I make sure I don't pack anything with high densities.
📄️ Broken RSA
I tried to send you an important message with RSA, however I messed up my RSA implementation really badly. Can you still recover the flag?
📄️ Ellipse Curve Cryptography
I overheard my professor talking about ellipse curve cryptography. I tried googling it, but didn't find anything so I implemented it myself.
📄️ Find The Lattice
As we've seen, lattices contain hard problems which can form trapdoor functions for cryptosystems. We also find that in cryptanalysis, lattices can break cryptographic protocols which seem at first to be unrelated to lattices.
📄️ No way home Back
Quantum Computers are going to break some of the standard cryptosystems like RSA, ECC and others. We're in some trouble, so why don't we make our own Quantum-Safe Key Exchange Protocol?
