Using quantum-safe hybrid certificates for signing documents
Channel: PKI Consortium
Date: 2023-12-07

Within the HAPKIDO project we aim to develop a roadmap for hybrid Quantum-Safe Public-Key Infrastructures. Next to TLS many other digital services rely on PKIs for their security; one important example is the electronic signatures on documents, which are standardized in PAdES and have legal value in many countries. One of the services which provides PAdES support is the european Digital Signing Service (DSS). To support the transition to quantum-safe PKIs we have created an extension for DSS, which allows users to use a hybrid certificate to sign and validate a PDF-document. In this presentation we will show our work and explain some of the decisions that we made in the process.
