Student thesis: Master's Thesis


As the evolution of system architecture of SCADA (Supervisory Control and Data Acquisition) system and the change of users’ requests in SCADA system the demand for information security is increasing in SCADA system In the past the system architecture of SCADA system was designed to monolithic in the situation which did not need to connect to others it toke no account of the system security As time goes on it uses the common system architecture gradually in SCADA system And the demand for remote monitoring which needs connect to Internet is also increasing Lack of the protection for system security in traditional SCADA system may cause damage to the user Nowadays industrial control system (ICS) and public infrastructure such as power systems adopt SCADA system Once bringing out damage on account of system insecurity it will have a very profound effect on the economy people's livelihood etc In [13] Comparing with other Public-Key Cryptosystem such as RSA McEliece and GGH NTRU encryption algorithm costs less computation time than other Public-Key Cryptosystem In the thesis we will use NTRU encryption algorithm to enhance the data security when transmitting data through Modbus in the SCADA system which requires real-time responses The mode in the thesis is called as SCADA/CCM and we will analyze the performance of SCADA/CCM
