in all over the world, the industries such as water, electric and gas are using
real time infrastructures for communication between field devices connected
within networks such as using
Local Area Network (LAN)/Wide Area Network (WAN)
or/and over internet to fulfill the requirements of industrial processing and
automation. Supervisory Control and Data Acquisition (SCADA) system is part
of ICS. This is system based on real-time processing infrastructure, system
control and design. In existing survey, several mechanisms/solutions were developed
for reliable delivery of data without any attack. Several techniques were also
implemented such as using Secure
Socket Layer/Transport Layer Security (SSL/TLS), secure shell (SSH) and Internet
Protocol Security (IPSec) for
securing data across internet and overcoming the attacks related with SCADA
communication. These techniques have also limitations in terms of data delivery
and security because these are based on TCP/IP protocol for communication and
on cryptography algorithms for the purpose of security. Based on detail SCADA
security analysis, the cryptography techniques have been adopted to enhance
the security of these critical systems. The proposed security solution takes
novel approach to implement the best security performance cryptography algorithms
included AES, RSA and SHA-2, as a security layer within Distributed Network
Protocol (DNP3) stack. This novel approach successfully enhanced the security
of DNP3 protocol as a part of SCADA system while comparing with end-to-end security
implementation.]]>Shahzad, A.A., S. Musa, A. Aborujilah and M. Irfan,201410652659Shahzad, A.A., S. Musa, A. Aborujilah and M. Irfan,20142014Musa, S., A.A. Shahzad and A.
