Sicherstellung der Vertraulichkeit von Informationssystemen durch Standardisierung von quantenresistenten kryptografischen Verfahren

Digitalisation and computer-aided or even fully automated systems have become an integral part of modern life, and society and the economy are now highly dependent on the internet and networked IT systems. However, modern technologies and achievements in these areas also harbour major risks. Ransomware attacks and scams regularly lead to financial losses for companies and citizens. This is why the term cybersecurity has become so widespread.
The continuous development of technology and scientific knowledge is now making it possible to usher in a new era of computing through quantum physics and mechanics. Quantum computers are poised to surpass the older computers of the previous century in terms of performance and redefine the efficiency of computing operations for specific requirements. However, we already know what consequences the potential performance of quantum computers will have on systems currently considered secure.
This has given rise to initiatives that take a preventive approach to corresponding risks in order to eliminate or minimise them before the first commercial quantum computer. This thesis examines whether the standardisation of quantum cryptographic procedures can help to protect the confidentiality of existing systems and their communication from the dangers resulting from the enormous computing power of quantum computers. In addition, it should prevent the security of our form of communication as we know it today from collapsing, as encryption is no longer considered secure.
With the help of expert interviews in the areas of software implementation, critical infrastructure, the public/military sector and quantum-resistant processes, the question of confidentiality through standardisation will be examined and a complete overview of the entire value chain will be provided.
