PQC

QKD in the German telecommunications network for enhanced IT security

Abstract Cryptographic primitives and protocols require constant modifications and adaptations in order to maintain the security of IT-systems. Many researchers argue that applying the notion of crypto-agility provides more feasible and practical updating of cryptographic systems, especially in the light of the expected transition to PQC.

Abstract Quantum computers threaten to fundamentally endanger the security of cryptography used today. In addition to the development of algorithms that are resistant to attacks by quantum computers, crypto-agility is an important field of research in order to be able to exchange algorithms in time and thus be safer from the impending danger.
