Definition ∞ Post-Quantum Security refers to cryptographic algorithms and systems designed to withstand attacks from quantum computers. As quantum computing capabilities advance, current encryption methods, which rely on the computational difficulty of factoring large numbers or solving discrete logarithm problems, become vulnerable. Post-quantum cryptography aims to develop new mathematical problems that are intractable even for quantum algorithms, ensuring the long-term security of digital communications and assets.
Context ∞ The development and standardization of Post-Quantum Security algorithms are subjects of significant research and regulatory attention. News often highlights the progress of cryptographic standardization bodies, such as NIST, and the potential timeline for transitioning critical infrastructure to quantum-resistant cryptography. The implications for blockchain security, particularly the protection of private keys and transaction integrity, are a primary concern for the digital asset industry.
