Post-Quantum Cryptography Basis

Definition ∞ Post-quantum cryptography basis refers to the fundamental mathematical and algorithmic principles that underpin cryptographic systems designed to resist attacks from future quantum computers. Current public-key cryptography relies on computational problems that quantum computers could efficiently solve, necessitating the development of new, quantum-resistant schemes. This involves exploring alternative mathematical problems, such as lattice-based, code-based, or hash-based cryptography. The objective is to secure digital communications and assets against an anticipated quantum threat.
Context ∞ The transition to post-quantum cryptography represents a critical security challenge for all digital systems, including blockchain networks and digital assets. Discussions frequently address the standardization efforts by national security agencies and the practical implications of deploying these new cryptographic primitives. Future developments will involve the gradual migration of existing systems to quantum-resistant algorithms, ensuring long-term data security in a post-quantum computing era.
