Definition ∞ Lattice-based algorithms are a class of cryptographic methods whose security relies on the computational difficulty of certain problems in mathematical lattices. These algorithms are considered strong candidates for post-quantum cryptography because they are believed to resist attacks from quantum computers, unlike many current public-key systems. They offer robust security properties and often produce relatively compact keys and signatures. This makes them a promising foundation for future secure digital communications.
Context ∞ News about lattice-based algorithms frequently appears in the context of global efforts to develop and standardize post-quantum cryptography, particularly by institutions like NIST. Discussions often center on their mathematical foundations, efficiency, and the challenges of integrating them into existing digital security infrastructures. A critical future development involves their widespread deployment across various applications, including blockchain networks and digital asset security protocols, to safeguard against potential quantum threats.
