Forschung

Christian mainly explores whether and how resource-constrained embedded systems can be secured against practical attacks. Especially the authenticated key establishment as well as the key management in combination with user-friendliness are of his major interest. His research includes:

  • physical layer security,
  • wireless security,
  • heterogeneous networks,
  • cognitive radio networks,
  • statistical signal processing, and
  • resource allocation for wireless communications.
