This document summarizes a student's master's thesis on using blockchain technology to improve cyber security for smart metering systems transactions. The thesis addresses motivation for securing smart metering systems, describing smart cities/grids and AMI architecture. It reviews related works applying blockchain for grid monitoring security and databases. The student proposes a private/public permissioned blockchain architecture called AMI-BC using a hybrid proof-of-efficiency consensus algorithm across cloud, fog and IoT tiers. It would secure smart meter readings and detect energy fraud/anomalies using machine learning models to predict consumption and power quality.

- Contribuir a mejorar la Security de las transacciones en los Sistemas de Medición Inteligente utilizando un mecanismo de cadenas de bloques que permitan garantizar la integridad, confidencialidad y disponibilidad de la información para garantizar la confianza entre los usuarios y la empresa eléctrica. El proyecto involucra analizar diversos esquemas de Cyber Security en las comunicaciones de Sistemas de Medición Inteligentes, que aporte mecanismos de protección de la información en los instrumentos de medición inteligentes (Smart Meters) que puedan ser implementados en nuevos dispositivos o adaptados a dispositivos ya existentes.
- Criptografía IDS Intercambio de claves Cadena de Bloques* Solutions: Cryptographic Authentications/PKI IDS Blockchain (currency, trading energy, supplychain, ID) Why our proposal is a good solution? Not implementations (Related Works). Perhaps novel BC solutions are appearing. Blockchains mechanish is a better solutions for Data Base Tampering than others solutions such as: PKI, Single Cryptograpy, IDS
