Internet of Things

Adding computer communication to otherwise dumb devices isn’t new. As far back as the 1990s, a whole list of Internet-enabled Coke machines around the world had varying functionality. The granddaddy of them all was the Coke machine at Carnegie Mellon University, set up in the 1970s.

Smart meters vulnerable to false data injection

Smart meters vulnerable to false data injectionThe power grid delivers electricity to charge iPads and run data centers. The power grid connect users with electricity producers through interconnected transmission and distribution networks. In these networks, system monitoring is necessary to ensure reliable power grid operation. The analysis of smart meter measurements and power systems are a routine part of system monitoring.

Help Net Security reports that most energy security professionals told nCircle they did not believe smart meters are secure enough. When asked, “Do smart meter installations have enough security controls to protect against false data injection?” 61% of the 104 energy security professionals said “no”. False data injection attacks introduce arbitrary errors into state variables while bypassing existing techniques for bad measurement detection to exploit the power grid.

Patrick Miller, the founder, CEO and president of EnergySec, noted, “Smart meters vary widely in capability and many older meters were not designed to adequately protect against false data injection. It doesn’t help that some communication protocols used by the smart meter infrastructure don’t offer much protection against false data injection either.”

“… we need to make sure that all systems that process usage data, especially those that make autonomous, self-correcting, self-healing decisions, assure data integrity,” Miller added.

Railroad Sensors Predict Derailments Wirelessly

Railroad Sensors Predict Derailments WirelesslyUnion Pacific (UNP), the nation’s largest railroad company, has deployed Internet of Things technology throughout its network. according to Dailywirless.org the IoT can predict certain kinds of derailments days or weeks before they are likely to occur. Theis will improve safety and avoid millions of dollars in damages.

According to the article, Union Pacific, which moves 900 trains a day, started using acoustic sensors 10 years ago to monitor noises from vibrations of ball bearings in train wheels. This allows the company to get trains off the track before a faulty bearing causes a derailment. More recently, the company started using visual sensors that can detect when wheels begin to flatten–another factor that can cause accidents on the rails.

Lynden Tennison, CIO at Union Pacific, told CIO Journal, that the company can now check 40 million patterns every day and can alert the train operators of any anomaly in a bearing within five minutes. “Our goal was to design a system that requires very little maintenance,” he said.

To do this, Union Pacific worked with Intel (INTC) which addressed some of the unique challenges of designing a wireless sensor network for a rail system (pdf). The blog states that to overcome the battery-life issues, Millennial Net paired its i-Bean wireless technology with “energy harvesting” technology from startup Ferro Solutions. An inductive vibration generates power to send [battery free] at 115 Kbps over a distance of 30 m,” said Tod Riedel, cofounder and vice president of business development at Millennial Net.

Are you ready for appliances that are smarter than you?

Are you ready for appliances that are smarter than you? Stacey Higginbotham at GigaOM asks “Are you ready for appliances that are smarter than you?” She points out that LG has introduced its first connected appliance, a Smart Thinq refrigerator that knows what’s inside it. The appliance can communicate with your phone. Your kitchen is about to get a similar level of connectivity as your living room.

The Smart Thinq refrigerator got a lot of press at the Consumer Electronics Show in Las Vegas as smart appliances were all the rage. The Android-based OS that enabled the fridge to communicate with your smartphone and share information like the contents of the fridge excited the press. The idea, according to the author, was that when someone got home from the grocery store they could choose to tell the fridge what was inside using a touchscreen or they could scan a bar code on their receipt that would contain the information about their purchases.

In this ideal world, the fridge would then be able to suggest recipes for the family based on their weight goals, age, gender and whatnot. If the consumer selected a fridge-offered recipe the appliance could shoot the recipe to the Smart Thinq oven and it could preheat. All of the connectivity occurs via Wi-Fi, and controled by the phone and in the touchscreen.

The article explains that other features include such as calorie counting and notifications of expiration dates. And if grocery stores take part – then the fridge could show when certain items are out and order them for home delivery.

Is Your Dishwasher Really Yearning for the Internet?

Is Your Dishwasher Really Yearning for the Internet? A startup called Ube thinks so. The firm is betting that smart devices and smartphone apps will make home automation cheap and easy.

In MIT’s Technology Review article “Is Your Dishwasher Really Yearning for the Internet?” Glen Burchers Ube’s chief marketing officer says that more and more home gadgets will ship with microprocessors, enabling the automation and remote control of everything from your lights to your laundry. Until this is a widespread reality, he’d like to sell you a wall outlet.

The wall outlet includes an ARM processor, runs Google’s Android mobile operating system, and can connect to the Internet. This means anything you plug into it can be controlled via your smartphone, and it will also track how much power your devices are consuming.

According to TR, the startup plans to sell the outlet along with a “smart” dimmer switch and plug for $60 to $70 apiece. The Austin, TX firm also plans to offer a free smartphone app that can control these and other Internet-enabled devices.

The blog reports that the Ube app will access a Wi-Fi network to scan for nearby Internet-enabled devices it can manage and lets you know what it can control. Mr. Burchers says the app can control more than 200 devices, most of which are gaming systems, set-top boxes, and TVs.

Mr. Burchers believes that Ube’s first products are just the beginning. He told TR most new electronics will be able to connect to the Web, and home builders will offer smart dimmers to new home buyers as they do granite countertops.

Internet of ThingsOnce upon a time, there was a time when “using the Internet” always meant using a computer. Today getting on the intertubes is an expected feature for many devices. The next digital frontier is the physical world, where the “Internet of Things.” The Internet of Things will bring online ability to objects.

Twine Sensor Connects Household Objects to the Internet

Twine Tested.com notes a Kickstarter project from two MIT Media Lab alums who developed a way to make the Internet of Things more available. A small, durable “Twine” sensor listens to its environment and reports back over Wi-Fi. The creators hope their new product will let regular users, even those without programming knowledge, digitally manage their surroundings.

A basic Twine unit senses temperature and motion, but other options like moisture detection, a magnetic switch, and more can be added using a breakout board. The various sensors and built-in Wi-Fi can be powered by either a mini-USB connection or two AAA batteries, which will keep it running for months. Twine readings get wirelessly loaded into the appropriately named Spool web app, where users can set simple if-then triggers that create SMS messages, tweets, emails, or specially configured HTTP requests.

For a donation of $99 or more will get you a basic unit when they ship in March.

THE SMART FRRRIDGE. Chilly Forecast for Internet Frrridge

Internet FridgeThe Smart Frrridge is a new version of the familiar kitchen apparatus. According to Medienturn the new fridge comes with a built-in computer that can be connected to the internet. It is one of a growing class known as “internet appliances” that include not only smart phones, but also web-enabled versions of typical household appliances.

The refrigerator keeps an eye on the food in it by using RFID technology, a digital camera and image processing. These technologies allow the fridge to keep track of whats in it, how long has this been there, should it be trashed?

To keep in contact with the Smart Frrridge all you have to do is to pick up your mobile phone and call. It will be able to suggest a menu that uses the foods inside, and generate a shopping list of the missing ingredients and place the order online.

The Smart Frrridge cab also be used to watch television, listen to music, to take a photograph, save it to an album, or post it to a website, or send it to an email recipient. The comes with a docking station you can just dock in your Apple (AAPL) iPod or iPhone and start using all your favorite cooking apps.

SCADA: How Big a Threat?

Cyber attackerThere are reports of two recent cyber attacks on critical infrastructure in the US. Threatpost says the hacker who compromised the water infrastructure for South Houston, TX, said the district used a three-letter password, making it easy to break in.

There are also reports that a cyber attack destroyed a water pump belonging to a Springfield, IL water utility. There are mixed reports that an attacker gained unauthorized access to that company’s industrial control system.

According to DailyWireless, Supervisory Control And Data Acquisition (SCADA) software monitors and controls various industrial processes, some of which are considered critical infrastructure.

Researchers have warned about attacks on critical infrastructure for some time, but warnings became reality after a highly complicated computer worm, Stuxnet, attacked and destroyed centrifuges at a uranium enrichment facility in Iran.

German cybersecurity expert Ralph Langner found Stuxnet, the most advanced worm he had ever seen. The cybersecurity expert warns that U.S. utility companies are not ready to deal with the threat.

In a TED Talk Langner stated that, “The leading force behind Stuxnet is the cyber superpower – there is only one; and that’s the United States.”

In a recent speech at the Brookings Institution, he also made the bigger point that having developed Stuxnet as a computer weapon, the United States has in effect introduced it into the world’s cyber-arsenal.

New NIST Report Sheds Some Light On Security Of The Smart Grid

NIST DarkReading reports the National Institute of Standards and Technology (NIST) released a report (PDF) by the Cyber Security Coordination Task Group. The report from the Task Group which heads up the security strategy and architecture for the nation’s smart power grid includes risk assessment, security priorities, as well as privacy issues.

The smart grid makes the electrical power grid a two-way flow of data and electricity allows consumers to remotely monitor their power usage in real-time to help conserve energy and save money. DarkReading says researchers have raised red flags about the security of the smart grid. Some have already poked holes in the grid, including IOActive researcher Mike Davis, found multiple vulnerabilities in smart meters, including devices that don’t use encryption nor do they authenticate users when updating software. He who was able to execute buffer overflow attacks and unleash rootkits on smart meters.

Tony Flick, a smart grid expert with FYRM Associates, at Black Hat USA talked (PDF) about his worries over utilities “self-policing” their implementations of the security framework. “This is history repeating itself,” Mr. Flick said in an interview with DarkReading.

According to DarkReading, the report recommends smart grid vendors carry out some pretty basic security practices:

  • Audit personally identifiable information (PII) data access and changes;
  • Specify the purpose for collecting, using, retaining, and sharing PII;
  • Collect only PII data that’s needed;
  • Anonymize PII data where possible and keep it only as long as necessary;
  • Advanced Metering Infrastructure (AMI) must set up protections against denial-of-service (DoS) attacks;
  • Network perimeter devices should filter certain types of packets to protect devices on an organization’s internal network from being directly affected by denial-of-service attacks;
  • The AMI system should use redundancy or excess capacity to reduce the impact of a DoS;
  • AMI components accessible to the public, must be in separate subnetworks with separate physical network interfaces;
  • The AMI system shall deny network traffic by default and allows network traffic by exception;
  • Consumers’ access to smart grid meters be limited. Authorization and access levels need to be carefully considered.

VA BPL Net RIP

The Manassas, VA broadband over powerline (BPL) network is dead. DSLReports cites the chief protagonist of the BPL drama the American Radio Relay League ( ARRL) which reports that on April 05, 2010, the Manassas City Council unanimously voted to pull the plug as of July 01 2010.

BPL was once praised as the third alternative to the telco’s and cableco’s stranglehold on the broadband market.  Former FCC chief Michael Powell called the Manassas installation, “the pinnacle of broadband achievement” just five years ago. In the mean-time increased broadband speeds and the unwillingness of utilities to become broadband providers made BPL irrelevant.

The BPL vendors saw the writing on the wall a while ago and have turned their attention to the “smart grid.” I wrote about IBM’s move into BPL as part of their “Smarter Planet“marketing move awhile ago (here). This is an easier space for firms like Comtek, Ds2 and International Broadband Electric Communications (IBEC) to play in. They won’t have to deal with that pesky FCC or end users since they can sell their products to utilities as part of  the U.S Department of Energy $3.3 billion smart grid technology development cash give away grants.
