Quantum computing poses an imminent threat to today's cryptographic protocols, requiring urgent migration to post-quantum cryptography. Most projects include common protocols like TLS, mTLS, QUIC, SSH, OAuth, IPSec and many more in their security implementation. This session demonstrates practical implementation of these protocols and approaches to migrating them using OpenSSL's post-quantum capabilities (ML-KEM for key generation and ML-DSA for signatures).
The presentation introduces a prototype framework that implements security protocols with both classical and post-quantum algorithms, enabling developers to understand protocol mechanics, migration challenges, and hybrid approaches. The framework uses OpenSSL and open source libraries such as LibOQS, OQS Provider, and StrongSwan to showcase real-world PQC integration.
The session explores the working of these migrations with existing open source projects, demonstrating real-world PQC integration patterns. Attendees will gain hands-on experience with PQC implementation and leave with actionable guidance for migration projects.
This session presents a comprehensive approach to post-quantum cryptographic protocol migration through both educational prototypes and real-world implementations. The demonstration includes a prototype framework that implements common protocols like TLS, mTLS, QUIC, SSH, OAuth, and IPSec with both classical and post-quantum algorithms, while also exploring how existing open source projects are handling these migrations in practice.
The session begins by demonstrating the prototype framework implementing common protocols with classical algorithms in a server-client scenario, helping developers understand how these protocols work at the code level. The presentation then identifies migration challenges for these protocols and showcases the prototype implementation with post-quantum support. Throughout this process, the session utilizes OpenSSL's classical and post-quantum capabilities specifically for key generation, exchange, and digital signatures. The examination covers practical challenges in PQC migration such as key size increases, performance impacts, and compatibility issues through prototype implementations.
Live examples include step-by-step protocol implementations with clear separation between protocol logic and cryptographic operations. Additionally, the session explores how these protocols with PQ support work within existing open source projects, examining their approaches, challenges faced, and solutions implemented.
The dual approach provides attendees with both educational clarity through simplified prototype implementations and practical insights from real-world deployments. The analysis covers concrete code examples from existing projects, migration strategies, and testing methodologies used by open source communities. The prototype framework serves as a learning tool while the real-world examples validate these concepts in practice.
This session targets developers, security professionals, and researchers interested in post-quantum cryptography implementation. Attendees will leave with both theoretical understanding from the prototype demonstrations and practical insights from existing implementations, supported by actionable guidance applicable to migration projects.
