  FPGA is a hardware architecture based on a matrix of programmable and
configurable logic circuits thanks to which a large number of functionalities
inside the device can be modified using a hardware description language. These
functionalities must often be secured especially when the context is sensitive
(military, banking, medical, legal, etc.). In this paper, we put forward an
efficient implementation of SIMON's block cipher algorithm using Xilinx Vivado
2018.2. The proposed design is analyzed through simulation on Xilinx Artix-7. A
prototype of our design is implemented using the xc7a35tcsg324-1 FPGA chip.
Performance and results are discussed.
