Abstract
The problem of data security in IEEE 802.15.4 systems on Pololu Wixel devices is solved, examples of hardware and software implementation of encryption and decryption of different devices on the same platform are given. The proposed approaches can be used in the development, implementation and operation of wireless enterprise, industrial, and personal systems. Possible areas of development for this work are related to research on improving encryption algorithms (increasing key length, using asymmetric ciphers, etc.), comparing their performance, and implementing a complete data exchange protocol. During the work there were problems in the implementation of encryption algorithms on low-power processors. During the work, a number of issues were resolved regarding type reduction, addressing, memory space, buffer overflow, and more. Issues resolved with reconciliation of receiver and…
