Communication Security for SCADA in Smart Grid Environment

Supervisory Control and Data Acquisition systems are basically Process Control Systems, designed to automate systems such as traffic control, power grid management, waste processing etc. Conventionally, SCADA is connected only in a limited private network because SCADA is considered a critical infrastructure, and connecting to the internet may put the society on jeopardy, SCADA operators hold back on connecting it to the public network like the internet. However, connecting SCADA to the Internet can provide a lot of advantages in terms of control, data viewing and generation. SCADA infrastructures like electricity can also be a part of a Smart Grid. Connecting SCADA to a public network can bring a lot of security issues. To answer the security issues, a SCADA communication security solution using crossed-crypto-scheme is proposed.
