There's been a lot of talk about some portion of the RSA keys on the Internet being insecure, with "2 out of every 1000 keys being bad". This is incorrect, as the problem is not equally likely to exist in every class of key on the Internet. In fact, the problem seems to only show up on keys that were already insecure to begin with -- those that pop errors in browsers for either being unsigned or expired. Such keys are simply not found on any production website on the web, but they are found in high numbers in devices such as firewalls, network gateways, and voice over IP phones.
It's tempting to discount the research entirely. That would be a mistake. Certainly, what we generally refer to as "the web" is unambiguously safe, and no, there's nothing particularly special about RSA that makes it uniquely vulnerable to a faulty random number generator. But it is extraordinarily clear now that a massive number of devices, even those purportedly deployed to make our networks safer, are operating completely without key management. It doesn't matter how good your key is if nobody can recognize it as yours. DNSSEC will do a lot to fix that. It is also clear that random number generation on devices is extremely suspect, and that this generic attack that works across all devices is likely to be followed up by fairly devastating attacks against individual makes and models. This is good and important research, and it should compel us to push for new and interesting mechanisms for better randomness. Hardware random number generators are the gold standard, but perhaps we can exploit the very small differences between clocks in devices and PCs to approximate what they offer.
Ethan Zuckerman — formerly of Global Voices, now at the MIT Center for Civic Media — has spent his career trying to find thoughtful, effective ways to use technology as a lever to make positive social change (previously), but that means that he also spends a lot of time in the company of people making […]
Earlier this month, I gave the afternoon keynote at the Internet Archive’s Decentralized Web Summit, and my talk was about how the people who founded the web with the idea of having an open, decentralized system ended up building a system that is increasingly monopolized by a few companies — and how we can prevent the same things from happening next time.
At this week’s O’Reilly Velocity conference in Santa Clara, Artur Bergman, founder and CTO, told the story of how he got involved in starting a denial-of-service-resistant CDN — a personal story about helping his old company cope with a titanic DDoS attack that brought it and its upstream provider to their knees.

Vaporizers that deliver a fast, controlled burn will set you back up to $300, which is why the FEZ Vaporizer (now just $99) is an absolute steal.The FEZ dry herb pen does everything that more expensive models handle at a reduced price. It heats up […]
Taking pictures can be challenging. There are a million factors that can influence each shot you take – and unless you’re a trained photographer, you often just focus, click…and cross your fingers.Of course, you can take some of the ambiguity out of your picture-taking with this Hollywood Art Institute Photography Course & Certification package, now […]
Experienced shutterbugs with DSLR cameras have boatloads of lens options for capturing the moment. Unfortunately, smartphone photographers often get stuck with their one crummy lens, which means limited zoom and focus for their final image.Step up your smartphone’s photographic power with the Acesori 5-Piece Smartphone Camera Lens Kit, now just $9.99 in the Boing Boing Store.Magnetic rings easily […]
