Freescale Trust Computing and Security in the Smart Grid


With the increasing deployment of automated technical solutions in the implementation of automated metering reading (AMR), advanced metering infrastructure (AMI) and smart grid infrastructure, possibilities of security attacks like data hacking, introducing malware in the system and cyber attacks are on the rise as well. Vulnerabilities in AMI devices include non-secure data buses, serial connections or remote access to debug port. The question arises: how can data security and customer privacy in smart meters and smart energy gateways be ensured? This paper talks about how trusted computing helps resolve security issues in implementing the smart grid by providing a clear idea of what elements of the system are trusted—and to what level and why. Freescale solutions that embed trusted computing are also covered.
