Introducing smart meters is making the electricity grid increasingly electronic, which saves time and money for utilities since they don’t have to send a person to read the meter. But this increasing ‘digitalisation’ also adds a lot more opportunities for tampering with the meters in some way, resulting in security vulnerabilities. These vulnerabilities obviously need to be considered before introduction of the smart meters to make sure everyone is paying their way when it comes to electricity. Chris Neill, Senior VP for Industrial and Medical Solutions Group at Maxim Integrated summarised the problem on the slide below. At the very earliest stage, meter SoC ICs could be replaced with fakes, but there are various measures already in place in the supply chain to try to combat this problem. At the factory, the meters are programmed with their software/firmware before being s...
