Abstract

The ZODIAC project has been exploring a security first approach to networking based on a new idea, the dynamic community of interest, based on groups of users with a demonstrable need to know. ZODIAC uses the most challenging network setting (the mobile ad hoc network) as a target, since each node must incorporate functions of both hosts and routers. The realization of the DCoI is a work in progress, but initial implementation results have shown that DCoI concepts can be translated into working systems. The current system applies virtual machine containers, extensive use of cryptography and digital signatures, dispersity routing, DHT-based naming, and explicit rate control among other advanced techniques. Putting security to the forefront in the design has led to interesting consequences for naming, authorization, and connection setup. In particular, it has demanded a hierarchical structure for DCoIs that …
