in the world. It is platform-independent and
can therefore be used in any microcontroller
and operating system configuration capable
of providing 1.5KB RAM and 6.5KB flash for
the licensing footprint. It is suitable for many
different devices – from smart headsets and
wearables to home automation devices,
smart city applications, smart meters and
countless other industrial sensors, actuators
and communication modules. The system
can be used, for example, with typical micro-
controllers such as the ARM Cortex M3/M4,
Intel Quark or AVR/Arduino and Raspberry
Pi or 8051, 68k, PIC/MIPS or MSP430 with
an embedded operating system or as bare
metal installation without OS. For all these
processors, Sentinel Fit offers the option to
implement asymmetric RSA encryption as
an off-the-shelf solution, which also allows
remote updates to enable or disable feature
access. As far as the technical specifications
are concerned, the microcontroller needs to
provide just 13KB RAM and 34KB flash for
the licensing footprint. For even smaller foot-
prints optional symmetrical AES encryption
is available requiring only 1.5KB RAM and
6.5KB flash. Because licensing is not limited
to specific microcontrollers or OS, it can be
used in any configuration. This makes it also
suitable for tablet or desktop processors, but
in those cases, use of an even higher level of
security is recommended. Having said that,
operating a smart sensor completely without
license protection is not advisable under any
circumstances.
Sentinel Fit is available in C source code and
integrates flexibly into existing embedded
toolchains. Due to its modular design, unnec-
essary functions are easily removed to achieve
an even smaller footprint. As the more power-
ful Sentinel RMS license management system
is already available for development environ-
ments such as Labview or Matlab and Sim-
ulink, the flexible, open source Sentinel Fit
can also be used here. It also offers a compre-
hensive modular kit for license and entitle-
ment management that ranges from licensing
tools to – optionally cloud-based – licensing
management systems for OEMs, and also pro-
vides interfaces to leading ERP and payment
systems for process automation. To this extent,
professional licensing systems differ signifi-
cantly from tools for generating a license key.
If developers decide to use these professional
tools, they automatically get the basis for the
flexible marketing of their solutions.

Figure 2. The more devices in the field are connected to the IoT, the more important it becomes –
for deployment and provisioning as well as licensing and reporting – to connect all these devices as
efficiently as possible.

Green Hills: Secure Platform brings wide
range of connected car services
Green Hills Software announced the integra-
tion of u-blox automotive connectivity and
positioning technology with the Green Hills
Platform for Secure Connected Car. The
Green Hills INTEGRITY real-time operating
system and Multivisor secure virtualisation
provide the trusted software foundation and
impenetrable partitions to securely and safely
combine Linux-based connected car services
with critical application and vehicle bus ser-
vices utilising u-blox portfolio of connectivity
modules.
ESCRYPT expands security portfolio
In future, IT security for the Internet of Things
will require a holistic approach. Because IoT
applications are increasingly interconnected.
This calls for lifecycle management and orga-
nizational integration alongside embedded
security solutions. In light of these develop-
ments, ESCRYPT is expanding the security
portfolio it offers its customers to include
backend services that parent company Bosch
has used for many years now to successfully
provide cyber security solutions in work-
places and production facilities worldwide.
ETAS: collecting measurement data for
automated vehicle systems
To develop and test the advanced systems
involved in vehicle automation, huge quan-
tities of data need to be collected at high
rates. ETAS has joined forces with partners to
develop a vehicle-specific solution. Smart sys-
tems that automate driving, connect vehicles,
and further mitigate their impact on the envi-
ronment are opening up a new class of vehicle.
In the case of vehicle automation, this calls for
exact monitoring of driving and environmen-
tal conditions, achieved by powerful sensors,
image processing, and object recognition sys-
tems.
Rohde & Schwarz: T&M tools to minimize
multi-region drive tests for LTE modules
Rohde & Schwarz is collaborating with wire-
less module vendor Gemalto to overcome the
problem of extensive real network drive tests
in different countries. The solution is to auto-
matically reproduce field-recorded network
configurations of Gemalto Cinterion modules
on an R&S CMW500 mobile radio tester.
ANSYS: Discovery Live enables real-time
digital exploration
ANSYS enables engineers to create smarter
designs faster and more efficiently with the
commercial release of ANSYS Discovery Live.
Discovery Live will empower millions of engi-
neers around the world to confidently sim-
ulate designs in real-time quickly and more
economically.
