Welcome to the web pages of the IT Security group!

Novel technologies like Cloud Computing, Ubiquitous Computing, Big Data, Industrie 4.0, and the Internet of Things do not only come with a huge demand for practical and efficient cryptosystems, but also with many novel attack surfaces. The security properties required from cryptographic building blocks for these innovative applications go beyond classical security goals.

Our mission is to provide a solid foundation for the design and mathematically rigorous security analysis of the next generation of cryptosystems that provably meet real-world security requirements and can safely be used to realize secure communication in trustworthy services and products for a modern interconnected society.
