DVB service security - A problem in development of multi-service television

The paper aims to discuss the issues those concern secure service delivery on DVB platform. Although the infrastructure exist, the end-users are still not fully satisfied with development and proliferation of new TV services. Because traditional DVB network security model has a partial nature and provides only a certain level of security, it is difficult to offer new multimedia services with assurances that the required security level will be held. This restrains successful deployment of new content delivery services on digital TV platform. To solve the problem, technical capabilities of the DVB based infrastructure have been explored in terms of service implementation aspects and potential evolution of services in the future. The paper does propose to use comprehensive, multi-dimensional measures necessary to secure the whole distribution way of a content. Such approach, assuring a given security level, seems to be essential for the successful service deployment in a new, personalized multimedia environment.
