Federal Office for Information Security (BSI)’s Guide on Developments in Quantum Technologies

The Federal Office for Information Security, also known as BSI (Bundesamtes für Sicherheit in der Informationstechnik), is the German federal agency in charge of managing communication and computer security for the German government.

This guide is intended to provide an overview of the most important developments in the field of quantum technologies from the point of view of IT security, as well as recommendations for action for migrating to quantum-safe cryptography. The transition to quantum-safe cryptography leads to numerous open questions (for example, the selection of suitable algorithms, necessary adaptations to protocols and standards, and many more), which are discussed in this document. As a basis for this discussion, the possibilities and the state of development of quantum computers are roughly described first. Then, the document discusses post-quantum cryptography and quantum cryptography in detail and distinguishes between these two complementary proposals.
