Evaluation of transmission secure methods in its systems

The essence of the operation of all ITS systems is to make decisions based on the information obtained and available. Under these assumptions, these systems are expected to utilize telecommunication, IT, automation and measurement technologies, which, in conjunction with advanced control methods, improve communication. Each ITS subsystem has specific requirements for communications channels that have to be tailored to the needs of the subsystem, its topology, and users, taking into account the costs of both the construction and operation of the system. The article presents issues related to information security analysis in ITS systems. Some selected aspects of risk prevention, which may be an important factor affecting the safety of the transport system, will be analysed. The analysis and evaluation of secure data transmission methods will also be conducted. This analysis and evaluation will select secure transmission methods using VPN virtual tunnelling technologies. In the article, the selected problems related to the security and confidentiality of information transmission between ITS elements and the provision of protecting access to the IT systems’ resources and their stored data, the aspects of problem affecting the communication system architecture is signalled. The methods for secure transmission in ITSs are secure transmission methods commonly used in systems, which require the confidentiality and security of information transmission between the data source and its recipient.
