Definition ∞ Lattice based schemes are a class of cryptographic algorithms whose security relies on the computational difficulty of solving certain problems in high-dimensional lattices. These schemes are a leading candidate for post-quantum cryptography, offering resistance to attacks from future quantum computers. They provide a robust alternative to current public-key cryptography methods like RSA and ECC. This mathematical foundation underpins advanced encryption and digital signature capabilities.
Context ∞ Research and standardization efforts for lattice based schemes are actively pursued by national security agencies and cryptographic communities globally. Their potential adoption is a key topic in discussions about long-term digital asset security and the resilience of blockchain infrastructure against quantum threats. News reports on cryptographic breakthroughs often feature progress in this area.
