Post-Quantum TLS Migration in Hybrid Cloud Environments
Summary
Hide β²
Show βΌ
Organizations are preparing for post-quantum cryptography (PQC) migration, focusing on hybrid cloud architectures. TLS protocol, used for communication between cloud and on-premises systems, is vulnerable to quantum-era threats. Upgrading to OpenSSL 3.5 enables quantum-resistant TLS key exchanges, but cloud provider support varies, potentially requiring a PQ TLS proxy. TLS hardening can be achieved now to protect data in-transit and reduce future quantum decryption risks. Financial services, healthcare, and government sectors are particularly impacted due to regulatory requirements and the complexity of their systems. The migration process involves inventorying cryptographic assets, upgrading protocols, replacing libraries, and validating integrations across thousands of systems.
