Abstract As technology advances, homes become more digitalized and evolve into smart homes. Bystanders, e.g. guests in smart homes, are often unaware of the smart home devices and the associated privacy risks that make them especially vulnerable.

Abstract Organizations have to plan on migrating to quantum-resilient cryptographic measures, also known as PQC. However, this is a difficult task, and to the best of our knowledge, there is no generalized approach to manage such a complex migration for cryptography used in IT systems that explicitly integrates into organizations’ steering mechanisms and control systems.

Abstract Asymmetric cryptography, specifically key exchange and digital signatures, enables secure digital communication. However, sufficiently powerful Quantum Computers, which could be available within a few years , would be able to break classical primitives like Elliptic-Curve Diffie–Hellman (ECDH) and RSA in polynomial time.

Abstract Widely used asymmetric primitives such as RSA or Elliptic Curve Diffie Hellman (ECDH), which enable authentication and key exchange, could be broken by Quantum Computers (QCs) in the coming years.

Abstract Selecting a library out of numerous candidates can be a laborious and resource-intensive task. We present the cryptolib index, a tool for decision-makers to choose the best fitting cryptography library for a given context.

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 The COVID-19 pandemic forced a number of companies to place their staff into home office. In terms of security awareness measures, this means that content or training can only be played out remotely.

Zusammenfassung Aktuell werden PQC-Algorithmen standardisiert, um der aufziehenden Gefahr für konventionelle asymmetrische Algorithmen durch Quantencomputer zu begegnen. Diese neuen Algorithmen müssen dann in bestehende Protokolle, Applikationen und Infrastrukturen eingebunden werden. Dabei ist mit Integrationsproblemen zu rechnen, die einerseits durch Inkompatibilitäten mit existierenden Standards und Implementierungen begründet sind, andererseits aber auch durch fehlendes Wissen der Softwareentwickler über die Handhabung von PQC-Algorithmen zustande kommen.

Abstract The rise of quantum computers poses a threat to asymmetric cryptographic schemes. With their continuing development, schemes such as DSA or ECDSA are likely to be broken in a few years’ time.
