Seguridad en el sistema de gestión de datos medidos de energía eléctrica aplicando cifrado homomórfico.

Abstract

The Ecuadorian electric sector is going through a great development due to the population growth and the implementation of new technologies, such in the generation field as in the distribution field. This has caused a raise of energetic consumption, and given place to an increase in the information flow through the Ecuadorian electricity network. On the other hand, information is a valuable and private resource that the electronic companies have to protect. For this, the new smart energy measurement devices could adapt to an homomorphic information encryption system, with the aim of safeguarding the users data. In this work the security of the files generated in the electric power data management system is studied and analyzed, and the fully homomorphic encryption is implemented to encrypt and decrypt files, so that the information is only accessible through a password or key, using tools of current development and relating to the theme. In addition, a comparison was made between the proposed encryption and other types of encryption, determining that the homomorphic cipher can use real numbers, unlike others that only use positive integers.
