Lattice-Based Signatures are a class of cryptographic digital signature algorithms constructed upon the mathematical hardness of problems in computational lattices. These signatures are considered a promising candidate for post-quantum cryptography, offering resistance against attacks from future quantum computers. They provide a method for verifying digital authenticity and integrity that is expected to remain secure even with advanced computational capabilities. Their mathematical foundations differ significantly from current widely used schemes.
Context
The development and standardization of lattice-based signatures are central to the global effort to prepare for the era of quantum computing. As current digital signature algorithms could be vulnerable to quantum attacks, the adoption of quantum-resistant alternatives like lattice-based schemes is critical for securing future digital communications and blockchain networks. NIST’s selection of Dilithium, a lattice-based algorithm, signals a major step towards their widespread implementation.
Integrating NIST ML-DSA signatures into Bitcoin's core protocol establishes a quantum-safe foundation, preempting the long-term threat to all digital assets.
