Hybrid Post-Quantum Cryptography Digital Signatures and Self-Sovereign Identity

Learn about implementing hybrid post-quantum cryptography (PQC) digital signatures within self-sovereign identity (SSI) systems in this 23-minute technical presentation from VTT Senior Scientist Erik Hieta-aho. Explore how combining classical ECDSA with the post-quantum ML-DSA signature scheme creates a hybrid approach that maintains current security while preparing for future quantum computing threats. Gain insights into the practical applications of SSI and digital credentials, particularly in the European context, and understand the benchmarking comparisons between hybrid, pure PQC, and classical cryptographic implementations.
