3. Introduction
O In the past, converting signals from analogue to digital was a great
invention which had a huge impact on scientific researches .
O Nowadays scientists are heading to digitize not only the signals but
also digitize every single detail in our life
O In order to get the maximum gain from the rapid growth of the
technology , Scientists invented the IOT(Internet of Things) which
connecting all facilities and life essentials through a big Network

4. Internet Of Things (IOT)
O Simply IOT is how to convert all objects
used in our daily life to smart devices
which can connect with each other
through a big network , in order to collect
,sense or exchange information.
O IOT is the best way to integrate the
physical world into computer-based
systems, and resulting in improved
efficiency, accuracy and economic benefit
in addition to reduced human intervention

5. Internet Of Things (IOT)

6. IOT main components
O One of the main components of the IOT devices is the
Sensors which is responsible for converting the information
from its physical form to a digital form.
O The other main component of the IOT devices is the core of the
device which should be either ASIC or FPGA or GPP
O Next slides will show which one of them is better to be used as
a IOT device Core

7. ASICs vs GPP vs FPGAs
O Application Specific Integrated Circuit (ASIC) is
an integrated circuit (IC) customized for a
particular use, rather than intended for
general-purpose use.
O It could be the optimum solution for the mass
production of devices which has a dedicated
permanent function (non-upgradable )

8. ASICs vs GPP vs FPGAs
O Both GPP (General Purpose Processor )and FPGA
have the same advantage on the ASIC which is
both can be reprogrammed and reconfigured.
O So which one of them should be used in IOT
devices ???
O Theoretically the processing capabilities and
power consumption of the IOT devices shouldn’t
be high

9. Security in IOT
O IOT networks are considered to be wireless networks .
O IOT technology depends mainly on collecting data and send it to a
data center to be analyzed and choosing the suitable actions.
O Since that there is an approach to widely use IOT in all fields of
the physical world.
O IOT devices frequently handle sensitive information, such as
command and control signals for smart homes, and automobiles
which should be transmitted securely through the air interface

10. Security in IOT
O The most important topics in Security
for IOT networks are :
 Encryption :
 Transmit the data securely between
parties.
 Authentication
 Be sure ,who will receive the data.
 Data integrity
 Be sure that the data will received
correctly.

11. Security in IOT
O Adding the term of Security in the IOT network
,creates constraints on the implementation methods
that should be used in the IOT devices.
O Adding security Algorithms will affect the processing
time and the energy consumption
O In this paper , the reason of preferring the HW
implementation over the SW one, will be discussed

12. High-Performance Low-Energy Implementation of
Cryptographic Algorithms on a Programmable SoC
for IOT Devices
O Due to severe power and timing constraints of the “things”
in the Internet of things (IOT), cryptography is expensive for
these devices.
O implementations of cryptographic algorithms in the
devices need to be upgraded frequently compared to the
longevity of these “things”.
O there is a critical need for having the following characteristics
in any cryptography implementation for IOT devices :
Reconfigurable low-power High-performance

13. O The software-based cryptographic operations are expensive in
terms of energy for IOT devices.
O The custom hardware implementation of the algorithm is a
viable option, as it can boost performance and have lower
power consumption compared to its software implementation.
O The FPGA clock speed is much slower than the clock on GPP.
However, the FPGA can complete the computation intensive
functions much faster than the software implementation.

Cryptographic Algorithms on a Programmable SoC
for IOT Devices

14. O Even though FPGA clock speed can be 10× slower than GPP, the
FPGA implementation can still be up to 3,000× faster.
O Compared to GPP, FPGAs do not have extra operations such as
instruction fetching or instruction decoding.
O Data paths on the FPGA are customized to the algorithm in order to
achieve its maximum computation efficiency.
O FPGAs have much higher energy efficiency in computationally
intensive applications.

15. O To evaluate the use of FPGAs as an energy-efficient
reconfigurable substrate for crypto-engines, the
following algorithms were used :
O AES (as a Symmetric Encryption Algo.)
O RSA (as a ASymmetric Encryption Algo.)
O SHA (as a Hash function )
O The Zedboard platform used in this paper contains the
Zynq 7000 SoC chip containing two ARM9 cores and
one Zynq 7000 FPGA.
