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.
Foundational research integrates lattice-based cryptography, utilizing the LWE problem's hardness, to future-proof blockchain security against quantum decryption.
