Why key management becomes the weakest link in a post-quantum and AI-driven security world

Key management (the process of creating, storing, rotating, and retiring cryptographic keys throughout their lifetime) is often overlooked in organizations despite being critical to security, and this gap becomes even more dangerous as post-quantum cryptography (encryption designed to resist quantum computers) and AI systems become more widespread. The real challenge of post-quantum readiness is not choosing the right algorithm, but building operational ability to safely rotate and manage keys across systems without downtime. AI systems introduce additional risks because keys protect not just data access but also AI behavior and decisions, requiring tighter key controls and more frequent rotation than traditional applications need.
