Abstract: The electrical grid is a critical infrastructure for modern society. It has been evolving into a smart(er) grid, allowing infrastructure aware decisions based on data collected in real-time from smart meters and other devices. Smart meters and their uplinks have, however, limited physical security due to their location within customer premises. DLMS/COSEM is a standard protocol for remote interactions with smart meters, often being deployed above power-line communication links. The paper presents the ValiDLMS framework, the first open source solution for validation and security auditing of DLMS/COSEM implementations using this communication profile. The framework was developed as an extension to Wireshark and was used to analyse an industry partner’s DLMS/COSEM implementation. The results show that ValiDLMS can effectively support the discovery of bugs and/or other non-conformance problems.
