Lattice cryptography is a branch of cryptography that uses mathematical structures called lattices to create secure encryption algorithms. These systems are considered resistant to attacks from both classical and quantum computers, making them a promising area for post-quantum cryptography. The underlying mathematical problems associated with lattices are computationally difficult to solve, providing a strong foundation for security. This field is critical for future-proofing digital security.
Context
