Quantum computers could one day weaken or even break the cryptographic methods we use today, thereby destroying secure communication. There are already numerous activities in the field of quantum resistant cryptography. But the way to a secure infrastructure is still a long way off. New procedures have to be checked in detail regarding their security. Their practical suitability can not only be determined theoretically, but must also be tested in real scenarios. Suitable procedures must be standardized and integrated into existing communication protocols. They can then take the first steps into practice via software implementations. However, this process can take many years, while state actors are already storing massive amounts of encrypted data traffic, only to break it years later. So w ...
