Cryptographic algorithm for protection of communication in drones control

The paper below presents an optimised cryptographic algorithm, designed to protect communication in the management of drones. In this communication the need for the data to be protected as much as possible and (in case) stored reliably rises. The use of microcontrollers requires an optimised algorithm in terms of number and type of operations, due to lower computing power and a small amount of memory. The algorithm is built on DES algorithm, according to the Feistel scheme. It is a 64-bits symmetric block cryptographic algorithm, using a 512-bits cryptographic key.
