What is lattice-based cryptography and how does it work?

Lattice-based cryptography is a type of cryptographic system that relies on the mathematical structure of lattices. It is considered secure against quantum attacks.

What are the advantages of using lattice-based cryptography?

Some advantages include resistance to quantum attacks, efficiency in key generation, and versatility in various cryptographic applications.

Can you explain how it compares to traditional cryptography?

Unlike traditional cryptography, which may rely on problems like factoring large numbers, lattice-based cryptography is based on hard problems in lattice theory, making it more secure against future quantum computers.

What are some real-world applications of lattice-based cryptography?

Real-world applications include secure communication protocols, digital signatures, and encryption schemes that are designed to be quantum-resistant.
