We present decoy routing, a mechanism capable of circumventing common network filtering strategies. Unlike other circumvention techniques, decoy routing does not require a client to connect to a specific IP address (which is easily blocked) in order to provide circumvention. We show that if it is possible for a client to connect to any unblocked(More)
| Smart Packets is a DARPA-funded Active Networks project focusing on applying active networks technology to network management and monitoring without placing undue burden on the nodes in the network. Messages in active networks are programs that are executed at nodes on the path to one or more target hosts. Smart Packets programs are written in a(More)
In this paper we survey issues and challenges in enhancing the survivability of mobile wireless networks, with particular emphasis on military requirements*. Research focus on three key aspects can significantly enhance network survivability: (i) establishing and maintaining survivable topologies that strive to keep the network connected even under attack,(More)
Experts have long recognized that theoretically it was possible to perform traffic analysis on encrypted packet streams by analyzing the timing of packet arrivals (or transmissions). We report on experiments to realize this possiblity using basic signal processing techniques taken from acoustics to perform traffic analysis on encrypted transmissions over(More)
There is an urgent need for a pro-active approach to botnet detection and mitigation that will enable computer network defenders to characterize emerging and future botnet threats and design effective defense techniques before these threats materialize. To this end, we have developed a System for Live Investigation of Next Generation bots (SLINGbot).(More)
Imagine a world in which every device has an embedded processor and a high-speed wireless link. Any two devices can talk to each other and you link devices together as needed to get your work done. Devices with embedded processors and wireless links are coming soon. This paper looks at some of the problems we have to overcome to make it possible to link(More)
This article introduces Smart Packets and describes the smart Packets architecture, the packet formats, the language and its design goals, and security considerations. Smart Packets is an Active Networks project focusing on applying active networks technology to network management and monitoring. Messages in active networks are programs that are executed(More)
The Internet is an extremely complex system, and it is essential that we be able to make accurate measurements in order to understand its underlying behavior or to detect improper behavior (e.g., attacks). The reality, however, is that it is impractical to fully instrument anything but relatively small networks and impossible to even partially instrument(More)
We present the architecture, design, and implementation of a Smart Environment for Network Control, Monitoring and Management (SENCOMM). SENCOMM uses active network technology to comprise a Management Execution Environment (SMEE), which coexists with other execution environments (EEs). Management applications, called smart probes, run in the SMEE. A probe(More)
