This blog post discusses the importance of post-quantum cryptography (PQC) and its implementation in Red Hat OpenShift Service Mesh 3.2. It explains how traditional cryptographic algorithms are vulnerable to quantum attacks and details various PQC algorithms. The author emphasizes the necessity for organizations to prepare for quantum threats and provides a step-by-step guide to configuring quantum-secure gateways using Istio. This ensures that communications remain secure against both classical and quantum computing attacks, addressing the urgency of transitioning to PQC to mitigate risks.
