Post-Quantum Primitives

Definition ∞ Post-quantum primitives are cryptographic algorithms designed to withstand attacks from large-scale quantum computers, which pose a theoretical threat to current public-key cryptography. These primitives include new encryption, digital signature, and key exchange schemes based on mathematical problems believed to be hard even for quantum computers. Their development is a critical effort to future-proof digital security infrastructure. They represent a fundamental shift in cryptographic design.
Context ∞ The transition to post-quantum primitives is a significant, ongoing initiative in cybersecurity and digital asset security, often reported in tech and crypto news. Organizations like NIST are standardizing these algorithms, impacting future blockchain protocols and digital signatures. The urgency stems from the potential for quantum computers to compromise existing cryptographic foundations, jeopardizing the security of cryptocurrencies and other digital assets. News frequently covers progress in standardization, new research, and implementation efforts across various industries.
