Last week at IETF 124, I participated in the IETF hackathon focusing on hybrid post-quantum signatures. With the Internet Draft draft-ietf-lamps-pq-composite-sigs-13 now nearing RFC status, the hackathon provided an ideal venue to validate interoperability and readiness of these next-generation cryptographic schemes.
SafeLogic implemented and tested hybrid signature scheme combining classical and post-quantum algorithms ( ML-DSA65 + Ed25519) to ensure compatibility with other participants’ implementations.
The results were very encouraging: signature generation and verification across multiple independent implementations worked as expected, demonstrating the maturity and growing ecosystem around post-quantum-ready hybrid signatures.
As the standard moves closer to publication, SafeLogic remains committed to enabling validated, quantum-resistant cryptography that integrates smoothly into real-world systems. Our participation in IETF 124 highlights that collaboration and interoperability testing are key steps in securing the future of digital trust.
