Design of secure communication protocol for Smart Grid

Rising smart grid networks are depended upon to have huge measures of data continuously created from various measuring devices like sensors, meters, electric vehicle charging stations, and so on which are installed in the power grid. Data created from these measuring devises must be passed on securely and safely to utility control places for wide-territory control and observing and to evaluate the general system status in an advantageous and correct way. The gathered information is moreover utilized as a piece of customer investment for enhancing power security. The secured transport protocol is required for such smart grid. Measurement data are described as secure and solid conveyance reliable delivery over utility-Wide Area Networks (WANs). On the other hand, our overview demonstrates that there is no surely understood transport protocol that can support the above attributes in an adaptable and light-weight way. Inspired by this, we plan a Smart Grid Secure Protocol, SGSP, exploiting the notion of a “State-token” which is issued with each node message and which is along these lines joined to relating customer message conveyed to the utility. Differentiated and existing clearly comprehended transport and security schemes, SGSP enables versatile server connection with each node when it is needed. In this paper, we discussed the need secure connection in smart grid and shows that way of establishing the connection between the each smart grid nodes securely.
