Forschung

In general my research focuses on privacy enhancing technologies and in particular:

  • Circumvention of Internet censorship, e.g., through multimedia steganography
  • Digital forgetting in the Internet: revocation of user data
  • Leveraging the security of Tor, e.g., against traffic analysis attacks
