AWS Payments Cryptography Adds Post-Quantum TLS Support to Secure Data in Transit

AWS Payments Cryptography now supports a new type of encryption called post-quantum TLS (PQ-TLS) to protect sensitive data as it travels across the internet. This technology helps businesses stay ahead of future threats from quantum computers, which could eventually crack today’s encryption methods. By using a new cryptographic tool called ML-KEM, AWS ensures that data sent through APIs is secure, even if quantum computers become powerful enough to break current security. This feature is available for free across all AWS regions and can be easily set up with the right AWS tools. It's a smart way for companies to future-proof their data security.
