  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 transmitter operation.
Examples of hardware and software implementation of encryption and decryption
of different devices based on Pololu Wixel are given in the paper. The basic
task of building a secure communication channel by encrypting data in the
channel was solved and firmware and application software were obtained to fully
validate the devices. In addition, this work has great application potential,
since the implementation of encryption in existing systems will have a small
impact on implementation and will not affect the project budget, but will
dramatically improve the security of data transmission in these networks. The
proposed approaches can be used in the development, implementation and
operation of wireless enterprise, industrial, and personal systems. Continuing
this work may be to test the performance of other protocols on this and similar
hardware for systems that may be embedded in short-range wireless communication
projects of short-range standards.
