GlobalSign Supports Billions of Device Identities In an Effort To Secure the IoT (globalsign.com) 28

Reader broknstrngz writes: GlobalSign, a WebTrust certified CA and identity services provider, has released its high volume managed PKI platform, taking a stab at the current authentication and security weaknesses in the IoT. The new service aims to commodify large scale rapid enrollment and identity management for large federated swarms of devices such as IP cameras, smart home appliances and consumer electronics, core and customer premises network equipment in an attempt to reduce the attack surface exploitable by IoT DDoS botnets such as Mirai.

Strong device identity models are developed in partnership with TPM and hardware cryptographic providers such as Infineon and Intrinsic ID, as well as other Trusted Computing Group members.

Comment Re:How many bits? (Score 2) 103

I work for Dolby Laboratories, and am deeply involved with high-dynamic-range content creation and hardware.

We created the SMPTE 2084 standard HDR EOTF (electro-optical transfer function.) It turns out that human perception is such that by choosing the luminance for code values to be just barely indistinguishable from the adjacent ones, you can get 0 to 10,000 nits (10x as bright as this Panasonic display) with only 12 bits. SMPTE 2084 is what all HDR TVs are using today.

The reason they have been searching for months for a diverse female lead is that they are looking for some real diversity. Hollywood has tons of tons of actors of every ethic or ethnic-mix persuasion, hoards of actors of every sexual persuasion and gender-identity, abundant of actors of every of religion you can imagine. But they wanted to push the envelope and find some real diversity.

They put out a lead casting call across all of Hollywood, seeking Actress who was Republican. Two weeks into the search they thought they finally had someone for the part, but it turned out to be Clint Eastwood in a dress.

Comment I saw a rig like this in 2005 (Score 1) 25

When I was shooting Fast and Furious: Tokyo Drift in Tokyo, in winter of 2005, I saw a rig a lot like this. I was walking down a street, and saw a van with four cameras, four LIDARs, and two GPS sensors on the top. I asked a man working on it what it was, and he said "Oh! Are you engineer?" and I confessed that I was just a movie-maker. But, nevertheless, they showed me everything in the van, and said that the point was developing 3D models of all the streets in Tokyo. At the time, it wasn't for self-driving cars though -- they wanted to build 3D in-car maps for navigation. The team of engineers was from a university in Tokyo; although I don't recall which one.

Comment Government? Is that really the issue? (Score 2) 55

While in the past, I agree that people were correct to hold the government accountable for this kind of surveillance, it isn't the biggest issue today. Huge amounts of information are gathered by companies about everybody on the 'net, and shared between them without any limitations. You don't want the government to see your email? Ok, fine -- but Google's incredibly powerful AI team doesn't just see your email -- it *understands* your email. Google can, and does, use that knowledge in any number of ways; and ways that will get more diverse (and perverse?) in the future.

In the not too distant future, I believe that companies like Google and Facebook will become more politically powerful than 99% of the governments in the world. Facebook was going to launch a satellite today to allow everybody in Africa to use Facebook; although somehow the rocket that was going to launch that satellite blew up. My belief is that Facebook wants to get information about everybody on the planet, and will do whatever it takes to do that.

Governments? Come on, that's not the threat.

Comment Fixed size arrays to handle unknown N items (Score 1) 674

Memory is cheap. Sometimes it's just plain faster and simpler to allocate an oversize fixed-size-array than to mess with dynamically allocating and freeing memory.

Fixed size arrays explode if N ever gets above your array size. There are many cases where you should NEVER do this... anything safety-critical or crash-critical or anything which might come under attack. However there are cases where you can assign an acceptable real-world practical limit on N and simply allocate an abundance of memory for it.

Comment Re:I really don't understand this drone applicatio (Score 3, Insightful) 43

My believe is that they intend to fly hundreds of these. If you have 100 tethers from 0 to 60,000 ft or so, I believe that you would have many aircraft accidents. Recall that the British used tethered balloons to protect themselves from German air raids. There is no way that you could see those tethers while flying, until you were very close to them -- then it would be too late to avoid.

There are a dozen or so tethered balloons around the border of the US now, so far there have been no incidents that I know of -- but the border is a place where pilots are very observant. Also, the balloons are only at about 10,000 ft or so, so most planes are far higher.

You can't change the angle at which the scene is rendered by interpolating between frames.

It's not the raw framerate. It's that the scene your viewing has to match where you're looking that quickly or you get motion sick.

Facebook is either going to fly a few thousand WiFi drones or thousands of WiFi satellites to cover the entire planet. Why would they be doing that?

OTEC has been "coming" forever, I went to a presentation that reads astonishingly like that Wikipedia article 40 years ago when I started college. The mechanisms were the same, the idea of using the energy to generate chemicals rather than send electricity through long cables was the same (back then they were suggested ammonia rather than hydrogen, but that's in the Wikipedia article too.)

Curious that the efficiency could be up to 6% -- now, granted, we're not using that temperature difference at all now, but still -- 6%? Solar panels can be up to 30% or more now.

If we were going to use OTEC for hydrogen to power, say, 10% of the cars in the world -- wouldn't we need tens of thousands of plants, each costing millions of dollars?
