Cryptography-Based Security Solutions:
Enabling Trust in New and Next Generation Computing Environments

Cryptography is an essential enabler of trust in complex IT systems such as the Internet of Things and cloud computing. Before CROSSING started, we found that cryptography and cryptography-based security solutions did not remotely meet all requirements that arise in new and next generation computing environments. We identified the inadequacy of current cryptography as a major hindrance to the development of trust in present and future computing environments and thus the beneficial development of society and economy. The overall goal of the Collaborative Research Center CROSSING is therefore to provide cryptography-based security solutions enabling trust in new and next generation computing environments. The solutions will meet the efficiency and security requirements of the new environments and will have sound implementations. They will be easy to use for developers, administrators, and end users of IT, even if they are not cryptography experts.

In CROSSING researchers from complementary areas such as cryptography, quantum physics, system and software engineering will achieve this goal in a collaborative effort. In the first funding phase of CROSSING, our innovative collaborative effort led to significant progress. Based on the results in CROSSING I, the second phase of CROSSING will be the next big step towards our overall goal. Protecting emerging computing environments and paradigms such as the IoT and cloud/edge computing from present and future attacks, e.g., by quantum computers, represents a major challenge that we will address. The further development of our tool CogniCrypt will connect our projects and allow for the secure integration of cryptography-based security solutions into applications. Collaboration between the diverse CROSSING research areas will remain a crucial success factor.
