New architecture for GOOSE and SMV messages

IEC 61850 is an international standard which defines communication protocols for electronic devices at electrical substations. IEC 62351-6 standard specifies the security mechanisms to protect real-time communications based on IEC 61850. GOOSE and SMV must be generated, transmitted and processed in less than 3ms.

While other alternatives have serious difficulties in achieving the target latency of 3ms, SoC-e’s design authenticates and encrypts real-time IEC 61850 data in less than 7µs. It is based on a novel hardware architecture in the form of Intellectual Property (IP) core, implementable in FPGA and able to process, cipher, decipher, sign and authenticate GOOSE and SV frames at wire-speed according to IEC 62351:2020.
