Post-Quantum Cryptography Intelligence
PQCRadar brings together everything you need to understand, explore, and navigate the transition to Post-Quantum Cryptography.
The Quantum Threat and Transition
The world's cryptography wasn't built to resist
quantum computers.
RSA, elliptic-curve cryptography, and other public-key systems secure much of the digital world around us. But the emergence of quantum computers could eventually break the security behind these systems, putting communications, identities, and digital assets at risk. What happens when the foundations of the systems we rely on are no longer secure?
01 · Today
Today's Cryptography
Public-key cryptography currently secures much of the digital world.
Widely deployed systems
RSA Cryptosystem
Public-key encryption and signatures based on integer factorization.
ECC
Public-key cryptography based on the hardness of elliptic-curve problems.
DH
Key exchange based on the hardness of the discrete logarithm problem.
Symmetric Cryptography
Shared-key encryption used to protect data at scale.
02 · Threat
Quantum Computing
Large-scale quantum computers threaten widely deployed public-key cryptography.
The main threat
Shor's Algorithm
Efficiently breaks RSA, ECC, DH and other systems.
Grover's Algorithm
Accelerates brute-force search, weakening symmetric cryptography.
03 · Response
Post-Quantum Cryptography
New cryptographic constructions based on problems believed to resist quantum attacks.
Prominent PQC families
Lattice-based
e.g., ML-KEM, ML-DSA
Code-based
e.g., Classic McEliece, BIKE
Hash-based
e.g., SPHINCS+, XMSS
Multivariate-based
e.g., MAYO, UOV
04 · Journey
Migration Ahead
A coordinated transition is required to build a quantum-safe ecosystem.
Migration roadmap
Inventory
Discover and inventory cryptographic assets
Assess
Evaluate quantum risk and prioritize targets
Replace
Implement PQC algorithms and hybrid solutions
Deploy
Roll out, monitor, and continuously improve
The quantum transition is not instantaneous. Migration takes time. Cryptographic inventories, protocol dependencies, certificate lifecycles, and deployed systems must be assessed before replacement can begin.
