Accelerating Adoption of Quantum-Secure Cryptography in the Real World
Our Purpose
The Post-Quantum Cryptography Coalition (PQCC) comes together as a community of technologists, researchers, and expert practitioners to drive progress toward broader understanding and public adoption of post-quantum cryptography (PQC) and the associated National Institute of Standards and Technology (NIST) standards. The PQCC will emphasize classical cryptosystems with quantum-safe security (vs quantum solutions) to enable information security in an era of cryptographically-relevant quantum computers.
