Zusammenfassung
Quantum computers threaten the security of asymmetric cryptography and thus the heart of a PKI - used for example to protect electronic data in passports. On the one hand, there are already promising candidates for post-quantum secure algorithms, but these also have disadvantages (stateful and / or with significantly larger public keys or signatures). On the other hand, there are some application areas for which a PKI should use post-quantum secure procedures as soon as possible. What is the situation regarding PQC in the market for secure, electronic identification (e.g. electronic travel documents)? What needs to be done to prepare electronic travel documents for a post-quantum world?
