Cybersecurity In Microgrids

Abstract

The following paper proposes a security scheme applied to microgrids, using symmetric and asymmetric encryption algorithms, digital signatures, hash functions, and SSL certificates to comply with confidentiality, authentication, and integrity aspects in a grid implemented with Raspberry Pi 3 nodes. The study presents the evaluation of different encryption modes to establish the final parameters in the construction of a security scheme. The results showed that the OFB encryption mode in AES is the most suitable for the length of common data in the transfer of information within such networks. In addition, the comparison between the symmetric encryption algorithm AES and the asymmetric encryption algorithm RSA showed that AES has significantly more efficient performance over RSA. Finally, the conclusions and future work are presented.
