This work presents a simulation model for point-to-point transmission of encrypted data using the application layer of Open Smart Grid Protocol (OSGP). The simulation aims to verify the integrity of the data transmitted from one point to another using Power Line Communication (PLC). The simulation model was developed in MATLAB and uses RSA, AES, RC-6, and 3-DES cryptographies to encode data. Data transmission uses PLC technique with Gaussian Minimmum Shift Key (GMSK) modulation. Results demonstrate that it is possible to use the OSGP protocol in the application layer with different criteria, which can be used according to the data size. It was applied a Additive White Gaussian Noise (AWGN) in the transmission to simulate the effects that exist in a real network. The experiments demonstrate that RC-6 outperforms the other cryptographic algorithms, presenting the smallest execution time, with low memory requirements.
