A Choice of Symmetric Cryptographic Algorithms based on Multi-Criteria Analysis Approach for Securing Smart Grid

In order to optimize production, consumption and distribution of energy, the different devices of a Smart Grid (SG) exchange daily increasing flows of information. Moreover, SG produces much more data stream than the traditional network. In addition to the large volume, the data of the SG are characterized by their diversity. However, securing these data flows is essential. Indeed, a single failure or attack could compromise the safety of the whole electrical network, the malfunction of which could have serious repercussions. Therefore, cryptography as a solution is necessary for SG to become realizable and secure. Being able to classify and to make a good choice of symmetric cryptographic algorithms for security of SG, we proposed to use an approach based on multi-criteria analysis.
