RF simulator for cryptographic protocol

Advances in embedded RF devices and sensor nodes have witnessed major expansion of end user services such as Internet of Things (IoT) and Cloud Computing. These prospective smart embedded and sensor devices normally interconnect to the internet using wireless technology (e.g. radio frequency, Wi-Fi) and run on top of CoAP and TFTP protocols. In this paper, we present a RF Simulator v1.1 which simulates lightweight security protocols for RF devices communications using Stop and Wait Automatic Repeat Request (SW-ARQ) protocol. The RF Simulator can be used for a quick trial and debugging for any new cryptography protocol in the simulator before actual implementation or experiment of the protocol in the physical embedded devices. We believe that the RF Simulator may provide an alternate way for a computer scientist, cryptographer or engineer to do a rapid product research and development of any cryptographic protocol for smart devices. The major advantage of the RF Simulator is that the source codes in the simulator can be used directly into its physical implementation of the embedded RF devices communication. We also presented simulation results of DHKE and AES encryption schemes using SW-ARQ protocol as a use case of the RF Simulator. The simulation was executed in ARM Raspberry Pi board and HP DC7800 PC as hardware platforms for the simulator setup.
