Lack of Predator video encryption raises questions

Readers express shock that broadcast signal was not protected

The story “Military Predator video intercepted by Iraqis" sparked some strongly worded comments by readers who were stunned that the military had failed to encrypt Predator video feeds and also questioned whether the initial Wall Street Journal story compromised national security.

A commenter named Dan was shocked to find that the military had known about the problem for at least a year. “That is not a technically savvy enemy, that is the military showing a severe lack of intellectual acuity,” he wrote.

An anonymous reader said all military communications other than public notices and news bulletins should be encrypted. “Why these drones ever deployed without every signal being encrypted is beyond my comprehension. It should have been part of the original design specification,” the commenter wrote.

Another anonymous reader agreed, stating that too much sensitive military information is available to the public and questioning the media’s decision to reveal information about the intercepted video feeds to the public.

“There is way more flow of information than we need to know,” the commenter wrote. “We spend all of this money for defense purposes, and then we divulge what many of us consider sensitive to the military’s mission. What happened to common sense?”

Yet another anonymous commenter noted that encryption can have an adverse effect on the real-time capabilities of drone video feeds. The military wants the video feed as close to real-time as possible, the commenter noted. "With encryption being another layer added, it’s going to increase the amount of time needed to transmit.”

The lack of encryption is plain silly, as the ability to intercept has clearly shown. Also, the statement that encryption introduces an undesirable delay is silly. At worst case, it should delay the transmission by one frame - at 30FPS. There is enough horsepower in modern FPGAs and other digital technology to convert a video feed (of any format, ie NTSC or digital) to MPEG in real time. I worked on one such system in 1994, and Moore's Law has been in effect since then, reducing the chips and power consumption. Look at the Xilinx Virtex and Spartan families. The Virtex family has up to 4 embedded PPC's, and you can always drop a uP core into an FPGA. If you can do MPEG in real-time, you can encrypt the same video feed in real-time. In fact, an encryption is easier. You can do it on a group of pixels really easily, and do the groups in parallel. (I also know of current systems that do per-frame analysis, in real-time. These are mainly for vision systems, which is more computationally intense than encryption.) The govt says 5 years to do the encryption - this is also silly - it should take no more than a year. If the govt is willing to throw some money at it - say $2..3mill, it could be done in 6 months. Development (NRE) is 6 months, production starts immediately after. BTW - I am an embedded systems engineer. This is the type of thing I do for a living. The encryption stuff is even off-the-shelf, and NIST is in the middle of qualifying more encryption algorithms. You could even generate a really simple algorithm as a stop-gap, and issue 10-sided dice to the troops (those who are not board gamers) to generate a key on a per-mission base.

There are programs that routinely encrypt real-time video for viewing an engagement (at speeds jigher than a UAVs) in real-time, not because its absolutely necessary but because IT CAN BE DONE! Here's another case of choosing a '1000 yr-old (by computer times) solution' to save a few bucks per unit OR using green recruits right out of school to architect a project, again to save money

This is ridiculous. We have to get waivers to test R&D systems transmitting unclassified data without encryption, but they're operating a tactical system in theater with no encryption at all? OK, so don't use the latest 384-bit or whatever encryption, but at least scramble the data with a cheap coder. The stuff is commercially available. I designed something better than this in a 14-pin PAL. Give me a break...

The "security" claim and criticizm of the media for reporting could be a red herring. If the media report that there was unauthorized intercept of the feed is true then the reporting isn't a security violation but an expose of the militaries failure to secure its communications and is what is at issue.

  • Where Cyberwarfare and Cybersecurity Meet

    We invite you to attend the third event in this three-part series on Cybersecurity. 1105 Government Information Group will present a panel of government and cybersecurity experts, including Jeffrey Carr, cyber strategies consultant and author of Inside Cyber Warfare; Dean Lindstrom, strategic cybersecurity architect and CEO of Cyberström LLC; and Dr. George Stein, director of the Cyberspace and Information Operations Study Center, Air War College, U.S. Air Force, in this editorial webcast on Tuesday, April 13 at 11 a.m., where they will discuss the cyberwarfare threat to both industry and government, as well as strategies to consolidate the wider cybersecurity mission.
