Post-Quantum Cryptography: Preparing For A Quantum Future
Security Boulevard, Wednesday, April 9th, 2025
As quantum computing continues to evolve, the security of our digital infrastructure is under increasing scrutiny. While quantum computers promise groundbreaking advancements, they also pose a significant threat to the cryptographic algorithms that protect sensitive information across the internet.
Enter Post-Quantum Cryptography (PQC) which is our path to quantum safe security. In this blog, we'll explore the background of PQC, the progress made by NIST and other organizations, and why businesses must act now to prepare their PKI and certificate lifecycle management systems for the quantum era.
The Need for Post-Quantum Cryptography
Traditional cryptographic algorithms like RSA, ECDSA, EdDSA, DH, and ECDH rely on the difficulty of certain mathematical problems, such as factoring large numbers or solving discrete logarithms. Quantum computers, once sufficiently advanced, could render these problems trivial through algorithms like Shor's algorithm, effectively breaking these cryptographic methods.
