Re: Security
@Victor: Absolutely correct! A tele-care application like that could save many lifes, it's a huge example of the IOT approach having the goal of the enhancement of people's safety. I hope thet you decided to further discuss about a project like this.

Re: Security
@etnapowers, a few months ago we were internally discussing about a project similar to that depicted in the presentation. Of course this kind of tele-care application monitors presence, actions, movements and displacements for a good reason.

Re: Security
In the case of PLC I'm not aware of readily available tools, but for WiFi/LAN/WAN penetration testing there are several Linux distributions containing all necessary tools. Probably the most popular is BackTrack Linux (now Kali Linux). It is officially a penetration testing environment and you can use it to test your network for robustness.

It should be possible to monitor WiFi network bandwith usage and detect activity levels from some specific devices (mobile phone, tablet, notebook, etc). I made several tests at home a few years before with BackTrack Linux 4 and I was surprised with the results.

Re: Security
@Victor--You are correct; PLC (Power Line Communications) and WiFi and DSL etc. all have security but it depends on how it is implemented.   We can hope that the power companies getting data from our meters using PLC are using correct security, but we won't konw until something goes wrong.

For WiFi, certainly the articles on the internet would tend to say a large fraction of home WiFi routers are not properly secured.  Are you aware of methods to monitor acivity over WiFi without actually snooping the data?  In other words, are you saying you could estimate data usage even with a properly secured WiFi router?

Re: Security
There are more subtle presence monitoring methods and one of them is WiFi/PLC network activity monitoring.

Re: Security
@eafpres,I couldn't agree more on this point. The consumpion monitoring is one of the modes by which the bad guys could control the presence of someone in a house, another example is a house for holidays. If the bad guys know the energy consumpion of the house during one year they can know the right period to visit that house because they are sure that none is there. They could monitor the energy consumption of many houses in this way and organize their illegal activity based on this data.

Re: Security
@etnapowers--security for the entire power system is definitely important.  A consideration is information that could be derived from, say, knowing the power consumption signature of a home.  If the bad guys got access to all the smart meter data, they could develop the signatures, then easily detect when it is likely no one is home from looking at changes in the use profile.  This is just one of many examples where not only is data integrity essential, but privacy will be very important.

Re: Security
Yes DaeJ, I think you're correct. The  security algorithm is however very important to be implemented in the smart meter system, according to me, so I wanted to underline its importance.

Re: Security
I think that secret key crypto through the digital signature would be a part of security algorithm. I believe that STMicroelectronics built the demo board related to smart meter to overcome the security issue.

Google "proved" the D-Wave 2 they operate jointly with NASA (mainly paid for by Google) can operate "up to ∼ 108 times faster".
I've written before about the impact the Internet of Things (IoT) will have on electronics sales including the special role played by analog devices in IoT.
Until about a decade ago, thermal energy was considered almost entirely as an analog, bulk phenomena.
Unless you live in a cave without any media access (which, I suppose, would preclude your reading this blog) you have heard about the Internet of Things (IoT).
With large scale integration of analog functions, we can probably bring eyesight to the blind.
