After years of vigorous development, the National Institute for Standards and Technology (NIST) published four official Post-Quantum Cryptography (PQC) algorithms in August 2024. These algorithms are rapidly transforming the cybersecurity industry as organizations must address the unprecedented prospective threat posed by cryptographically relevant quantum computers. ABI Research has previously covered how the Hardware Security Module (HSM) market is leveraging PQC algorithms, but another important market worth examining is Public Key Infrastructure (PKI).
