Control of Security of Cyber Train Gateway

The presence of many moving elements in case of trains is the specific problem of railway transport infrastructures. The security of moving elements within the cyber-physical system (CPS) needs, therefore, to be ensured against both physical and cyber intrusion. We will deal with the cyber gateway of the train, which is called a mobile communication gateway (MCG). It is associated with problems of the standard cyber gateway and the problems specific to the moving systems. It is impossi-ble to secure communication between train and control centrum through a closed communication system only, it need to take place through open space because of extensive infrastructure with assistance of ground communication gateway (GCG). The MCG design shall ensure the security functions of the gateway as well as sufficient communication capacity. Our control over environmental conditions of MCG is limited because it is in open space, both physical and cyber, often in motion. The MCG, there-fore, needs to be able to respond dynamically to environmental changes caused by deliberate attacks or unintentional changes in the system. The ability of the adaptability must be given to the MCG in design
