Definition ∞ Lattice-based assumptions are mathematical problems rooted in the study of lattices, which are regular arrangements of points in space. These problems are considered computationally hard for both classical and quantum computers. Cryptographic systems built upon these assumptions offer a promising approach to achieving quantum resistance. They form the basis for constructing public-key encryption and digital signature schemes that can withstand attacks from future quantum algorithms.
Context ∞ As quantum computing advances, the security of current cryptographic standards is a growing concern for digital assets and blockchain technology. News in the crypto space increasingly references lattice-based assumptions as a foundation for post-quantum cryptography. Researchers and developers are actively exploring and implementing these methods to future-proof digital security protocols against potential quantum threats, ensuring the long-term integrity of digital transactions.
