The Future of Privacy in a Post-Quantum World

Quantum computing represents a profound paradigm shift. While cryptographically relevant quantum computers (CRQCs) do not yet exist, experts predict they could arrive within the next decade. When they do, they will effortlessly break the public-key cryptography (RSA, ECC) that currently secures the internet.

The "Harvest Now, Decrypt Later" Threat Adversaries are currently capturing and storing encrypted data. Their strategy is simple: wait until quantum computers are available to decrypt it. For data with long-term sensitivity (state secrets, medical records), the quantum threat is already here.

Post-Quantum Cryptography (PQC) The global cryptographic community is racing to develop quantum-resistant algorithms based on mathematical problems that even quantum computers find difficult, such as lattice-based cryptography.

Organizations must begin their cryptographic agility initiatives now, inventorying their current encryption usage and planning the complex migration to PQC standards to secure data for the future.
