The chair deals with both the analysis and design of block ciphers. With "Pholkos", a so-called tweakable block cipher was developed that can work with up to 512-bit message blocks and is based on AES-like structures. Tweakable block ciphers could be an important building block for post-quantum secure symmetric systems in the future.
