This blog post presents a solution for automatically replicating card payment keys across AWS Regions using AWS Payment Cryptography. It provides high availability, resilience, and disaster recovery capabilities for payment transactions by securely replicating encryption keys and associated metadata across geographically dispersed Regions.

Specifically, the article covers:

• Card payment key management challenges and security risks with current key sharing practices
• Overview of the cross-Region replication (CRR) solution architecture and workflow
• Detailed walkthrough of deploying the CRR solution, including setting up the initial key exchange using TR-34 and key replication using TR-31
• Testing the solution by creating, importing, and deleting payment keys across Regions
• Disabling and cleaning up the deployed resources
• Security considerations for maintaining the highest level of protection for sensitive payment data
• Conclusion highlighting the benefits of the CRR solution and potential future enhancements
