What is Post-Quantum Cryptography (PQC)?
Post-Quantum Cryptography: Cryptographic algorithms engineered to remain secure against decryption attacks by future cryptanalytically relevant quantum computers.
Detailed Explanation
Post-Quantum Cryptography (PQC) focuses on developing and deploying mathematical algorithms (such as lattice-based, code-based, and multivariate cryptography) that cannot be solved by quantum computers running Shor’s or Grover’s algorithms. PQC protects long-term sensitive data against "Harvest Now, Decrypt Later" adversary campaigns.
Why PQC Matters for Enterprise Security
- Neutralizes the imminent obsolescence of RSA and Elliptic Curve Cryptography (ECC).
- Protects critical enterprise secrets, IP, and financial assets from future quantum decryption.
- Aligns with emerging NIST post-quantum standardization mandates.
