  1. Peter Mildenberger Johannes Gutenberg-University Hospital, Mainz, Germany Secure and Interoperable Teleradiology Solutions based on Open Source Standards

  2. Use Cases • Teleconsultation • Teleradiology • for central reference center • regional TR-Projects in Southern Germany • Research cooperation • VICORA Project, with 9 Universities, one Dep. for Medical Informatics, two industrial partners

  3. Goals • Establishment of secure datalinks with various and independant external partners. • Exchange of selected medical data by using standards. • Integration into the existing IT-infrastructure. • Easy to use and maintain, respecting legal requirements and privacy

  4. Motivation for Standardization IT-Working Group (@GIT) of the DRG

  5. Format of Datatransfer OpenPGP-compatible • DICOM-Object / • DICOM - email (Suppl. 54) • any file format encryption with compression PGP/MIME

  6. Mechanism to ensure complete transmission of all images (date, messages…) on the recipient site Also mechanism to ensure complete transmission for the sender (by receipt from recipient) Authentification and integrity of messages (signature) Supporting MIME Standards[1], esp. Multipart Mail, Message Partial und der Verwendung von X-Tags [1] incl. RFC2045/46 (MIME Part 1&2), RFC3156 (MIME Security with OpenPGP) Ideas

  7. Supporting secure variants of POP, IMAP… (optional, may become legal requirement in Germany) Encryption according OpenPGP using only the „MUST“-criteria, (ZIP as optional) Digitale Signatur (PGP / MIME) PGP/ GnuPG for Encryption and Signature acc.to RFC 3156 und RFC 1847 both ways are recommended: Encryption and signature in one step (combined method, RFC 3156, Kapitel 6.2) Data with seperated signature acc RFC 1847 PGP kompatibel encrypted (encapsulation, RFC 3156, Kap.6.1). Ideas
