Cryptography, which refers to the encryption of information, forms the basis of modern security systems. It provides the foundations that enable, for example, secure web surfing and shopping, email encryption, and cryptocurrencies.
As in the entire sub-discipline of IT security, researchers in the field of cryptography must always take into account the future. As new technologies progress, such as the development of quantum computers, existing cryptographic methods can be solved. The challenge here is to develop sustainably secure encryption methods that also protect data from unauthorized access in the long term, but at the same time are so efficient that they can be implemented in a wide variety of (small) devices.
In the Cryptography research area, world-leading scientists investigate sub-disciplines of modern cryptography, including, among others:
The research achievements of CCS members in the field of cryptography are not only leading nationwide, but have also been internationally recognized and visible for more than 20 years.
Researchers are embedded in an innovative, interdisciplinary, and international research environment. Important links here are particularly the affiliation with the Horst Görtz Institute for IT Security (HGI) – one of the largest and oldest institutes for IT security in Europe – and with the Cluster of Excellence CASA: Cyber Security in the Age of Large-Scale Adversaries, which is based at the HGI. The Center of Computer Science is also closely involved with the Bochum-based Max Planck Institute for Security and Privacy.
