Analysis of information secure transmission methods in the intelligent transport systems

The essence of operation of all the ITSs is to make decisions on the basis of the obtained and available information. The relevance of taken decisions depends on the quality of available information, its accuracy and up-to-dateness. It is important to pay attention to the fact that requirements for up-to-dateness of information as well as the consequences of delays in their transfer or in connection with their loss are different depending on the subsystem. The paper presented the issues related to the analysis of the ITS telecommunications environment. The selected aspects of prevention from risks, which may be an important factor affecting the security of the transport system functioning, will be analysed. Moreover, the analysis of methods for the secure data transmission will be also carried out. The transmission security methods will be selected within the framework of VPN virtual tunnel technologies. The mechanisms, the implementation of which will allow to increase the security and availability of information transmission in ITSs, were offered.
