 Hello from the ST stand at Embedded World 2016 here in Nuremberg. Now the internet of things has developed incredibly over recent years and will no doubt continue to expand. Jean-Luc Blanc is an application engineer from ST. Let's talk a little bit about how your ST safe A devices are improving security in this IOT world. ST safe is a turnkey solution that comes to help customers increase the security of their IOTN devices. It comes with a complete package with an expansion board and with a software code example that customers could use to increase their security. The ST safe A it comes in two package the S8N package and a really small QDFN 2x3 package we believe that will fit the PCBs device requesting a really small PCBs. So Jean-Luc give me an example of a typical threat and how ST safe A can help protect us. IOT is everywhere and so are the threats. Let's look at this smart city demo. We have lights each lights are equipped with a bulb each bulb connected to ST safe A chip. Something's wrong the light there's something wrong with light. In fact what has to be done is to connect the network the light the street light network to an administration server and to execute an authentication of each of the street lights. As you could see the genuine street lights are authenticated and are switched on the one that is not authenticated is kept off and put in quarantine. And is this important because some malicious hacker may use a city's lighting system to access the whole network. Exactly having this kind of doing this authentication helps to protect the network and this is where ST safe could bring another value but it's not the only security function that could be provided by ST safe A. ST safe A is doing authentication based on elliptic curve pictography 256 or 384 bits elliptic curve but can perform also some security service on establishing secure connection with servers like in TLS session and can manage and protect the asset of customers and device manufacturer. And am I right in thinking this this adds the necessary security to the standard microcontroller that's in the IOT device. Yeah using ST safe the customer could contribute to develop his application and rely on ST safe A for the security aspect. ST safe A has been developed and using a platform a hardware platform that rely to the highest standard the common criteria standard. This one has been evaluated EL5 plus this is a higher like in the banking area. Well as I said at the start the internet of things is growing daily and so are security worries so it's clearly something that's going to be very popular. Jean-Luc thank you so much for talking to us. Thank you Chris.
