With increasing digitization, the number of long-lived systems and services increases rapidly. For example, digital archives, such as electronic health record databases or land registry databases, are supposed to operate for many decades or even centuries. Ensuring the security of such long-lived systems is indispensable.

Unfortunately, most of the security technology used today appears inappropriate for protecting long-lived systems. This is particularly true for many cryptographic solutions. Cryptographic keys chosen today may be too short in the future and new attacks may threaten the security of systems which are considered secure today. Ensuring the security of long-lived digital systems is an important scientific and technological problem.

This website aims to be a platform for researchers and practitioners that enables the discussion of scientific challenges and the development of theoretically sound and practical solutions for the protection of long-lived systems.


This website is currently managed by the research group of Professor Johannes Buchmann, TU Darmstadt, Germany.
