Summary

Hide ▲

Organizations face a complex, multi-year migration to post-quantum cryptography (PQC) to secure hybrid cloud architectures. Hybrid cloud environments, particularly in financial services, healthcare, and government sectors, rely on Transport Layer Security (TLS) for communication between cloud and on-premises systems. These systems are vulnerable to quantum-era threats. Upgrading to OpenSSL 3.5 can provide quantum-safe TLS for on-premises systems. However, cloud-side support varies, requiring potential deployment of a PQ TLS proxy for end-to-end encryption. Proactive TLS hardening can mitigate quantum decryption risks now, with minimal disruption.

    OpenSSL 3.5 Introduces PQC Support for TLS Key Exchanges

    OpenSSL 3.5 has introduced post-quantum cryptography (PQC) support into TLS key exchanges, allowing organizations to upgrade to quantum-safe TLS with minimal disruption. This development is crucial for hybrid cloud environments, which rely on TLS for communication between cloud and on-premises systems. Some cloud vendors already provide post-quantum TLS functionality, while others plan to include it in their roadmaps. Organizations may need to deploy a PQ TLS proxy to achieve end-to-end quantum-safe encryption, depending on their cloud provider.
