<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">"Can Your Car Be Hacked?", "Hackers Reveal Nasty New Car Attacks", "New Targets for Hackers, Your Car and Your House", "Researchers reveal methods behind car hack", "Car hackers use laptop to control standard car", "Car hacking code released at Defcon". The listed above are just few of the articles regarding car hacking published in the last month alone!</span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">Due to the proliferation of on-board computers, vehicle connectivity, smart infotainment systems and telematics devices, car hacking is becoming an eminent threat to car owners.</span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">Components of our modern vehicles are constantly communicating between themselves: your gearbox gets RPM reading from the engine and speed data from the wheels and shifts gears accordingly. For the sake of simplicity, carmakers are using a very basic message based architecture named CAN bus. Interoperability and mixed fleets required harmonized data transmission systems, so the manufacturers developed few protocols that enable such connectivity. </span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">As most modern vehicles are now also equipped with cellular connectivity to allow navigation, browsing, video and audio streaming and transmission of car status & location.</span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">This high-tech cocktail creates a real fear to car owners, since the same system compromises the safety of the vehicle. As hackers with some automotive knowledge can intercept the car computers via the telematics and even alter its parameters: report lower speed and demand more torque, disabling breaks and changing engine revs.</span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: center;">

<div dir="ltr" style="text-align: left;">
<span style="font-size: large;"><br /></span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">In the recent automotive shows we noticed the creation of a new field called Car Cyber Security.</span></div>
<div dir="ltr" style="text-align: left;">
<span style="font-size: large;">One of the leading firms in this segment is <span style="color: black;"><a href="http://www.ariloutech.com/">Arilou Technologies</a>.</span> The Company developed a small CANbus based firewall that also authenticates the legality of the on-board devices and the incoming messages. Several automakers are examining Arilou's solutions.</span></div>

<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;">During the last decades, with the proliferation of satellite
services, cellular communication and mobility, many firms entered into the vehicle
t<u>racking and tracing</u> business, offering simple location services. The main usage
of such services is in the event of <u>vehicle theft</u>. Is mostly used by
professional operation centers that can, in some cases, even <u>rescue the stolen
assets</u>.</span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;"><br /></span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;">As time passed, such firms enriched the offering, by adding
more services such as: t<u>emperature monitoring, door opening and graphic
presentation of all assets on a map</u>. This fact gave fleet owners the freedom to
monitor assets on the move, converting soon to a real fleet management system.</span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;"><br /></span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;">Recently, more sophisticated devices can connect into the
data communication bus of the vehicle (CANBUS) and read part of the flow of mechanical
parameters between the different on-board computers. The raw data can be stored
or transmitted to the fleet manager. But such crude data have no use for the
owner, as it contains huge amounts of codes, without any feasible way to sort,
digest and define an action.</span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqe61SeEaO9tAsZP7ztshWrAXAfrxWDAAuk_YC6SEKy_jATTTUBym92B8Q3mxZsVtJp8_dMj7tOiEWEXh4SyaG1vq9aSpR7tokJ8wgNyiIpcR0bzFG49jZMyXdHC4UvW3VS2If64Mg7UMN/s1600/profit+engine.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqe61SeEaO9tAsZP7ztshWrAXAfrxWDAAuk_YC6SEKy_jATTTUBym92B8Q3mxZsVtJp8_dMj7tOiEWEXh4SyaG1vq9aSpR7tokJ8wgNyiIpcR0bzFG49jZMyXdHC4UvW3VS2If64Mg7UMN/s320/profit+engine.png" width="320" /></a></div>
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;"><br /></span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;">As a matter of fact, all those systems are cost-centers
for fleet owners, as they are paying modest monthly fees but getting the payoff
only in case of problem. Therefore the industry is moving toward <u><b>converting
telematics to a profit-center</b></u>.</span></div>
<div class="separator" style="clear: both; text-align: center;">
</div>
<div class="separator" style="clear: both; text-align: center;">
</div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;"><br /></span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;">Only a handful of the top telematics providers is capable of
analyzing the diagnostic trouble codes. <a href="http://www.traffilog.com/" target="_blank">Traffilog </a>for example, added several
layers of <u>Business Intelligence (BI)</u>, by selectively collecting data, analyzing
it at the vehicle level and transmitting only meaningful events and
action-driven alerts to the fleet manager.</span></div>
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;"><br /></span></div>
<br />
<div class="MsoNormal" style="direction: ltr; text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif; font-size: large;">The art of telediagnostics does not stop here: Traffilog can
even predict future failure of components and schedule <u>predictive maintenance</u>
cycles, based on real-time data analysis. The data are correlated with GPS
location and G maneuvers, as well as with other analogue or digital sensors.</span></div>

Telediagnostics</span></b><b><span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;"> </span></b><span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">is a multidisciplinary
field, composed of Telematics and Diagnostics. It refers to the ability to
read, correlate, analyze and transmit real-time information regarding vehicles,
its mechanical status, location, safety and other relevant data. <o:p></o:p></span></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">The major beneficiaries
of telediagnostics systems are fleet owners that can improve safety,
performance, saving and efficiency of their vehicles.<o:p></o:p></span></div>

<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">In-car connectivity
devices are taking care of Location Based Services and infotainment
systems. Such devices are featured with GPS antennas and SIM operated cellular
modems. <o:p></o:p></span></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">

<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">At the old times we
could detect faulty engine valve by it sound and a compression problem with
simple manometer.<o:p></o:p></span></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">Nowadays, with highly
sophisticated vehicles, all the monitoring is being done by numerous on-board
computers.<o:p></o:p></span></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">So once the technician
is connecting the diagnostics computer, he can easily understand the mechanical
status of the vehicle and its components. The data includes Diagnostics Trouble
Codes (DTC), last installed software versions and much more. The same computer
also resets the on-boards chips and upgrades the firmware.<o:p></o:p></span></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<br /></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">Few of the leading
telematics providers, such as</span><span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;"> </span><span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;"><a href="http://www.traffilog.com/" target="_blank"><span style="color: blue; mso-bidi-font-size: 11.0pt;">Traffilog</span></a> are combining an in-depth
automotive engineering knowledge with complex algorithms capable of sorting all
the on-board data, analyze it and then create meaningful events and alerts,
delivered in real-time to the fleet owner, the security officer or maintenance
manager.<o:p></o:p></span></div>

<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">The recipients can take
an immediate action regarding the vehicle and the driver, such as to guide him
to the closest repair shop, to alert the driver on evolving problem or any
other measurement.<o:p></o:p></span></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<br /></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<span style="font-family: 'Times New Roman', serif; font-size: 13.5pt;">This fascinating field
is going to grab all commuters' attention. We foresee that the tendency of more
and more on-board devices, Machine to Machine (M2M) and Vehicle to
Infrastructure (V2I, V2X) will increase in the upcoming years, so the next
generation vehicles will communicate with each other and with the road signs,
re-route the trip to avoid traffic jams and collisions. <o:p></o:p></span></div>
