Some notes on why crypto backdoors are unreasonable

Today, a congressional committee held hearings about 'crypto backdoors' that would allow the FBI to decrypt text messages, phone calls, and data on phones. The thing to note about this topic is that it's not anywhere close to reasonable public policy. The technical and international problems are unsolvable with anything close to the proposed policy. Even if the policy were reasonable, it's unreasonable that law enforcement should be lobbying for it.

Crypto is end-to-end

The debate hinges on a huge fallacy, that it's about regulating industry, forcing companies like Apple to include backdoors. This makes it seem like it's a small law. The truth is that crypto is end-to-end. Apple sells a generic computer we hold in our hand. As a user, I can install any software I want on it -- including software that completely defeats any backdoor that Apple would install. Examples of such software would be Signal and Silent Circle.

It seems reasonable that you could extend the law so that it covers any software provider. But that doesn't work, because software is often open-source, meaning that anybody can build their own app from it. Starting from scratch, it would take me about six-months to write my Continue reading

Interop Liveblog: IPv6 Microsegmentation

This session was titled “IPv6 Microsegmentation,” and the speaker was Ivan Pepelnjak. Ivan is, of course, a well-known figure in the networking space, and publishes content at http://ipspace.net.

The session starts with a discussion of the problems found in Layer 2 IPv6 networks. Some of the problems include spoofing RA (Router Advertisement) messages, NA (Neighbor Advertisement) messages, DHCPv6 spoofing, DAD (Duplicate Address Detection) DoS attacks, and ND (Neighbor Discovery) DoS attacks. All of these messages derive from the assumption that one subnet = one security zone, and therefore intra-subnet communications are not secured.

Note that some of these attacks are also common to IPv4 and are not necessarily unique to IPv6. The difference is that these problems are well understood in IPv4 and therefore many vendors have implemented solutions to mitigate the risks.

According to Ivan, the root cause of all these problems originates with the fact that all LAN infrastructure today emulates 40 year old thick coax cable.

The traditional fix is to add kludges….er, new features—like RA guard (prevents non-routers from sending RA messages), DHCPv6 guard (same sort of functionality), IPv6 ND inspection (same idea), and SAVI (Source Address Verification Inspection; complex idea where all these Continue reading

Lawmakers criticize FBI’s request for encryption back doors

U.S. lawmakers are skeptical of an FBI request for Congress to mandate encryption workarounds in smartphones, with critics saying Wednesday that back doors would create new vulnerabilities that bad guys can exploit.It’s currently impossible for smartphone makers to build in back doors that allow law enforcement agencies access to encrypted communications but also keep out cybercriminals, witnesses and lawmakers said during a hearing before the IT subcommittee of the House of Representatives’ Oversight and Government Reform Committee.Law enforcement representatives called on lawmakers to find a way to allow access to encrypted data as a way to prevent serious crime. Late last year, FBI Director James Comey called for a public debate on encryption after Apple and Google announced they would offer new encryption tools on their smartphone OSes.To read this article in full or to leave a comment, please click here

Airbnb’s new app for tablets features magazine-style layout

Airbnb has developed a new app customized for iOS and Android tablets in an attempt to give those users a better way to browse its million-plus home rental listings than with the devices’ web browsers.The free app, to be released Wednesday, lets users navigate its content as if they were flipping the pages of a magazine. Airbnb, founded in 2008, already has mobile apps for iOS and Android smartphones.The tablet app emphasizes big, high quality photos of people’s homes arranged on the screen in varying layouts, which can be easily flicked through. With the tablets’ larger screen size, pages for individual listings also feature photos and links to similar listings, resembling the look of a print magazine’s sidebar article. Rotate the tablet from a horizontal to vertical position, and the app’s interface will reorient itself.To read this article in full or to leave a comment, please click here

Social media helps curb Nigerian election deathtoll, paving future path

The dozens of deaths that marred the recent Nigerian elections would be considered shocking by the standards of most developed nations. Compared to past elections, however, the violence this time around was limited, and many observers say social media and technology such as biometric card readers played a big role in minimizing conflict.Online services are credited with keeping people informed during the runup to the elections, promoting the feeling they could communicate and express their views without resorting to violence, and other technology helped to ensure cheating would be kept to a minimum. Nigeria’s experience suggests that tech can play a role in reducing election-related violence in other countries.To read this article in full or to leave a comment, please click here

IDG Contributor Network: New algorithms could keep drones from crashing into people

Major delivery firms are experimenting with drones for deliveries. If you've started to experiment with drone flying for fun, you'll know that it isn't easy. There's a steep learning curve, and they crash quite a lot, I've found.However, it doesn't have to be like that. Collision avoidance is technically feasible. The drone senses objects and diverts.One of the issues with that, though, has been that developers only have a certain amount of time and money to develop new features. Those features have, thus far, been the tempting, seductive ones, like "follow-me" where the hobbyist drone follows the pilot like a dog on a leash. It's the latest thing.To read this article in full or to leave a comment, please click here

Google Fi app surfaces on Play Store, though most can’t use it yet

The Google Fi app showed up for the first time Wednesday on the Play Store: The catch is that you'll need a Nexus 6 phablet and an invitation to the new wireless service in order to make any use of it. Google's Project Fi, unveiled last week to mixed reviews, offers a potentially lower cost wireless service whose magic includes a SIM card that enables your Android device to bounce between Sprint and T-Mobile LTE networks as well as WiFi hotspots. Initially, the mobile virtual network operator (MVNO) service will only be available on the Nexus 6.To read this article in full or to leave a comment, please click here

PC prices to go up later this year, Gartner warns

PC prices have enjoyed record lows for many years now, but buyers might have to shell out a few more bucks for their desired laptop or desktop later this year. Research firm Gartner is sounding the alarm that PC prices might go up later this year due to recent currency fluctuations. The effect may especially be felt in Europe and Japan, where local currencies are weakening against the U.S. dollar. The alternative to rising prices is fewer features. PC makers might opt for less memory, a cheaper webcam or a lower-capacity hard drive to avoid higher prices. PC makers do something similar every holiday shopping season when they sell computers at rock-bottom prices.To read this article in full or to leave a comment, please click here

Massive China market offers even more upside for Apple

Although Apple announced record revenue from its Greater China sales region this week, the company's strategy has enough legs to push the market into the No. 1 spot on its books, analysts said today."It may take a couple of years, but China can become Apple's biggest," said Jan Dawson, chief analyst with Jackdaw Research.MORE: 10 mobile startups to watch The Americas, dominated by the U.S., remained Apple's largest sales region in the March quarter, generating $21.3 billion or 37% of the $58 billion total.
