High-Performance Key Management Scheme for Secure SCADA Communication

SCADA networks have important role in modern industries and infrastructures. Thus, secure SCADA communication is important for industries and infrastructures.Key management scheme is essential for secure SCADA communication. This paper presents and evaluates new and highperformance key management scheme by using CCS scalar multiplication and compact SD modular multiplication for encryption and decryption. The results demonstrate that the proposed CCS compact SD key management scheme provides an improvement in terms of the number of required multiplication steps compared to other key management schemes.
