Abstract:
The article deals with security of communication in a sensor system combining a wireless RF network and Ethernet. The article deals with design of complete secure sensor system combining a wireless RF network and Ethernet. Within the suitable sensor system topology design the requirements for the fast and efficient data exchange between individual logical system layers are taken into account. One of the major requirements for our design was to develop solution with minimum computing power consumed by the communication sensor nodes. The particular system layer security is based on the known security methods and protocols (TLS protocol, improved Diffie-Hellman protocol GDH.3), which have been extended by the methods needed for their practical use (method called AVOM, which is intended for discovering and labeling of all RF network devices). A partial goal of the designed solution is to improve the robustness of the implemented security mechanism for wireless logical group security key establishment.
