Lattice Cryptography

Definition ∞ 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 ∞ The current discourse on lattice cryptography is primarily driven by its potential to offer robust security against emerging quantum computing threats. Discussions frequently revolve around the development of practical lattice-based encryption schemes, their efficiency compared to current methods, and their integration into existing cryptographic protocols. The ongoing research aims to solidify lattice cryptography’s role in securing digital assets and sensitive data in the quantum era.
