Financial institutions and infrastructure providers have initiated multi-year cryptographic modernization programs following the publication of finalized post-quantum cryptography (PQC) standards by regulatory authorities.
Assessment of Vulnerable Legacy Systems
Legacy Public Key Infrastructure using RSA and ECC algorithms faces eventual decryption risk from quantum hardware. Audit teams are currently identifying exposed endpoints, encrypted data stores, and long-lived session keys across enterprise networks.
Implementation Roadmaps and Performance Costs
PQC algorithms introduce larger key sizes and increased processing overhead. Network teams report throughput penalties of 3% to 12% on encrypted tunnels during initial pilot deployments, necessitating hardware security module upgrades.
