A SCADA system operates as a control center of a central termination which receives information from one or more remote terminals and issues commands to them. To increase the security of systems encryption can be used to protect data transfer and storage. In this paper, we have suggested a safe environment in SCADA networks to create a proper communication between control center and RTU using key management protocol, mutual authentication And digital signature. So the server can ensure the security and non-manipulation of received and sent data. For this purpose, we use Hyperelliptical curve cryptography. Hyperelliptical curve is so suitable in cases where we have power, storage and time limitations as it needs fewer calculations and parameters in compared to other cryptography schemes such as elliptic and RSA. for example, 80-bit space is required for the HECC field whereas in ECC, 180 bits and in RSA, 1024 bits are required.
