Multiparty Communications Security

The goal of this project is to study security issues in the context of multipoint communications. Multipoint communications encompass several models ranging from the usual 1-to-N pattern of multicast to the generalized N-to-N scenario. In the initial stage, the project addresses the key distribution problem in multicast communication. The main design criteria are scalability and security with large dynamic recipient groups.

Solutions derived from common asymmetric techniques are first explored. Spreading of symmetric algorithms along the multicast tree will further be investigated at the next stage of the project in order to exploit the higher performance of symmetric techniques for bulk data encryption. Multicast on Internet and web proxies in caching will be addressed next as the application of the secure multicast schemes developed in the project.
