Post-Quantum Cryptography: Unlocking Security with Lattices 🔐

Speaker: Noah Stephens-Davidowitz, MIT Abstract: Much of the internet relies on public-key cryptographic protocols to keep sensitive information private. Unfortunately, the protocols that we currently use are known to be vulnerable to attackers with quantum computers. Recent advancement in quantum computing has therefore started a bit of a rush to replace our current protocols with protocols that are secure against quantum attackers. In this talk, I’ll describe the leading candidate for post-quantum cryptography: lattice-based cryptography. We’ll see a basic scheme, see the many benefits of lattice-based cryptography, and discuss some of the downsides and risks involved.
