Framework Enhances Firmware Security for Smart Grid Systems

/ 1 min read

🔌🔒 New framework enhances firmware security for smart grid systems. A proposed digital signing and verification framework aims to bolster the security of firmware updates in smart grid infrastructures, which are increasingly targeted by nation-state actors. This framework, designed for resource-constrained devices like smart meters, leverages Public Key Infrastructure (PKI) alongside Concise Binary Object Representation (CBOR) and Object Signing and Encryption (COSE) formats to ensure efficient data encapsulation and robust security. By addressing vulnerabilities associated with the convergence of information technology (IT) and operational technology (OT) attacks, the framework enhances the reliability and stability of smart grid systems while mitigating performance issues linked to device limitations.
