Security solutions of intelligent transportation system's applications with using VANET networks

Abstract

The paper deals with the problem of security increasing of applications oriented to safety used within intelligent transportation systems (ITS). The mainly part is orientated to the Lane Departure Warning System (LDWS) with connection to vehicular communications (VC). Simultaneously the safety parameters of the effective digital signature schemes for VC communications are mentioned which are used for an authorised message transmission. In the paper the possible solutions of detection of horizontal road marking on the base of segmentation method are described and the solution of connection of assistance service to Vehicle-to-Vehicle (V2V) communications with using Elliptic Curve Integrated Encryption Scheme (ECIES). Practical part realized via SW Matlab detects the departure of the vehicle from its driving lane, triggers the resulting alarm which is on the security manner transferred as alarm message with digital signature between vehicles via V2V communications. The effectiveness of three digital signature schemes according to length of the key is simulated via SW OpenSSL.
