What is Post-Quantum Cryptography?

Post-Quantum Cryptography (PQC) is a set of cryptographic algorithms designed to withstand attacks from quantum computers while remaining deployable on classical computing infrastructure and interoperable with existing network and application protocols. Expanded Explanation 1. Technical Function and Core Characteristics PQC refers to public-key algorithms that security researchers design to be resistant to attacks using large-scale quantum computers. These algorithms provide encryption, digital

What we add

Graph

A glossary entry defines a term and stops there. It doesn't show where the term is actually being used or written about. We track and link every article that covers it.

Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.

Articles mentioning this entity 87 Organizations tagged 16 Organizations AgilePQ, CryptoNext Security, evolutionQ, ISARA, LuxQuanta, PQShield, QNu Labs, Quantropi, QuantumShield, Quantum Xchange, QuintessenceLabs, QuSecure, SandboxAQ, Technology Innovation Institute, Terra Quantum, VeriQloud Related terms Related terms (co-occurring topics)

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Post-Quantum Cryptography for a real decision: a shortlist, a vendor comparison, a purchase. "Post-Quantum Cryptography makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
