Experiments for Embedded Protection Device for Secure SCADA Communication

Communication and security functions are considered to be the basic requirements to the electronic devices in the future power grid. Considering limited resources of the embedded field devices, developing the embedded protection devices poses a big challenge in building up the smart grid. This paper shows overhead for computing cryptographic algorithms at the device, and the performance degradation caused by incoming packet processing at embedded system devices. For this analysis we do some experiments on the operation which simulates message exchange in the SCADA system based on the IEC 61850. We also consider the security protocol for secure message exchange in the SCADA system. And then we consider the multi-core processor solution for implementing all required functions on the embedded devices as one possible approach.
