Based on the work of the ISHTAR, the TRUSTHEALTH1, the EUROMED- ETS and the MEDSEC project funded by the European Commission, the synergetic results of these different projects in providing a security infrastructure for the test environment of an oncological network will be demonstrated.

The ISHTAR project investigated security issues in Health Care Establishments (HCE). It provides guidance for threat and risk analysis, and defines a schema for specification and implementation of appropriate security services and mechanisms to respond to the HCE security requirements of both communication and application security concepts.

The TRUSTHEALTH 1 project dealt with specification and test implementation of basic security services and mechanisms based on Health Professional Cards (HPC) and Trusted Third Party (TTP) services.

Within the EUROMED-ETS project, the security solution has been extended to the Internet environment and WWW tools, successfully creating an Internet-based international TTP structure between the universities of Athens, Calabria, and Magdeburg.

Finally, in the MEDSEC project the specification and implementation of a generic EDI security solution has been delivered to provide secure communication between applications and sites.

In the ongoing TRUSTHEALTH2 project, the results of all these projects will be implemented in a real environment of cancer care.
