The Military Aims to Develop 'Smart' & Secure WiFi

Krishna Dagli writes to mention a Network World article about a military project to create a self-configuring, secure wireless network. From the article: "Academic concepts such as artificial intelligence and Tim Berners-Lee's 'Semantic Web,' combined with technologies such as the Mobile Ad-hoc Network (MANET), cognitive radio, and peer-to-peer networking, would provide the nuts and bolts of such a network. Although the project is intended for soldiers in the field, the resulting advances could trickle down to end users. 'Military networks are going to converge as closely as we can to civil technologies,' says Preston Marshall, the program manager of DARPA's Advanced Technology Office."

      Wireless ad hoc nets have two major points of vulnerability: they are vulnerable to routing protocol attacks, and they consist of nodes with finite energy reserves.

      While true for generic networks, your first point does not apply to the network in this situation.

      In a normal MANET, untrusted nodes are able to connect to the network and provide/receive services. However, in a military network, only trusted nodes will be allowed to join the network since you don't want an enemy to have access to your resources.

      Now, the question is, how do we have trusted nodes? We can't allow access based on hardware since there is always the risk of a node being captured by the enemy, (and we might sell the equipment to our allies). This means each node will have to have some sort of certificate that allows access to the network. Since each node must have a certificate, we can encrypt our routing protocols, preventing them from being attacked directly. (Actually, the hard part of the problem is certificate revocation.)

      Finite energy reserves are a problem, normally, but this is the military. If each node in the network costs US$1000, they deploy 10,000 of them and they only have power for 1 day, this is only US$10 million per day. This would only be a 1-2% increase in the cost of the war in Iraq. Well worth it if it helps fight a war. When ones dies, you drop off another one from a helicopter. If you want them transported by infantry, you just give them more to carry, or replacement batteries for the one they carry.

      If we use (good) encryption for the physical layer, meaningful traffic can't be injected and sniffing the channel provides no information other than communication is occuring. However, using frequency hopping, spread spectrum and other techniques you can actually get the signal below the threshold of noise making it essentially undetectable. Also, it makes jamming difficult since the jammer would have to jam all of the frequencies used instead of the small band used in a specific time slice. Ex: If you hop over 10 frequencies, and it appears random from the viewpoint for the attacker, they must jam all 10 frequencies at all times. If you use spread spectrum to spread the signal over 10 times the actual bandwidth required, this requires 10x the jamming also. So, if you transmit at 1 watt, they have to use 100 watts to jam you. This makes them nice targets for high-speed anti-radiation missiles (HARM).

    In the meantime, here are some reasons this is (even?) harder than it sounds.

    "we'll probably keep the security work a little more isolated": offhand that sounds like it will never work. They're going to need security from the MAC layer upward and it's going to affect almost every decision they make.

    It's a well studied problem, but one example of what you need to think through is the "hidden transmitter problem". It is possible to interfere with someone that you cannot hear.

    TCP needs to be tweaked or replaced: packet loss doesn't mean the same thing in a chaotic RF world as it does on an Ethernet segment.

    Media access policies need a lot of thought. Plenty of mesh algorithms have hit the wall when it came time to scale up the network. Again, as with routing, there are solutions but they haven't had as much time to grow up as TCP/IP has.

    Hard problems make for fun projects. They should structure this so that they get something useful even if one of the ingredients fails: they're trying to do a lot of hard things at once. This kind of project is why we need DARPA: no sane private company would attempt this.

  22. Decentralized C&C by QuantumFTL · · Score: 1

    The low-level details of these decentralized networks will be critical, but I am personally much more interested in the problems of applying this network to decentralized Command and Control in near-future urban combat. Squads will likely be temporary formations managed by decentralized algorithms. Dispersion of combat data will likely use gossip-like protocols and other ideas taken from modern P2P. The use of probabilistic flooding search will likely be more difficult because while networks like Gnutella have rapidly changing connectivity, they tend to retain the same basic statistics and topology. Because of rapid changes in a mobile network's connectivity statistics, the criticality threshold for probabilistic flooding as described by percolation theory will likely fluctuate as well, making it difficult to effectively operate near the transition region, where the number of flooded requests is minimized while still retaining good coverage.

  25. Old idea, new spin by Anonymous Coward · · Score: 0

    This kind of stuff has been around (for decades) on digital radio systems. Ericsson's is called EDACS, its a 9600 baud trunking control channel which is used to tell mobile radios which voice frequency to use. Modern 911 call centers have computers that dispatchers use to talk to fire/police/ambulance crews. There can be a lot of people wanting to talk all at once. Modern radios usually only have 20 or 30 channels to pick from, so they pick an electronic channel which is more like a database entry. If someone else is talking on a channel, and someone from another talk group wants to say something to everyone else on the same talk group, when they key up, the system automatically finds an empty frequency, tunes everones radios to that new frequency (without anyone lifting a finger) and everyone hears what is being said. Doing the same with wifi (best empty channel, least nodes/best performance using Dijkstras shortest path algorithm, and having things happen automagically is merely an extension on an old theme (although a cool one). There are already grid wifi networks too, so this technology actually fuses two existing technologies (one on a different platform) into something new.

    The problem with MANET is that of any matrix network: end points become bottlenecks. If there is only one node that has a connection with a gateway (quite normal in mobile environments) it ends up taking all the traffic of all the other nodes, which can become a bottleneck, a single point of failure and a target..

    Not to mention that such excess activity will lean heavily on battery powered equipment (read: the most critical node is likely to fail first).

Wired, wireless or satellite - the network should be smart enough to use whatever means it has, but dumb enough to not care about what kind of traffic it routes, just that it does as good a job as possible with the available hardware. Automatically multi-link, it would route most of your p2p traffic through fibers while your VoIP goes wireless to your headset. Built-in authentication and encryption to keep your gadgets in touch and your data secure, even though you use someone elses hardware as well as let other use yours.

    With the IFDL, each pilot is free to operate more autonomously because, for example, the leader can tell at a glance what his wing man's fuel state is, his weapons remaining, and even the enemy aircraft he has targeted. This link also allows additional F-22 flights to be added to the net for multi-flight coordinated attack.
