Establishing Trust on VANET Safety Messages

摘要: We introduce a new scheme for safety message authentication in VANETs. For practical implementation of VANET, we anticipate that road side units (RSUs) are not physically protected and prone to several different attacks including node compromise attacks. Thus, an RSU should be automatically trusted by on vehicles. In our proposed scheme, controller (RSC) is responsible controlling all the RSUs, delivering messages through RSUs vehicles given area, where each uses proxy signature mechanism based Elliptic Curve Cryptography (ECC), which variation known ECDS-based schemes modified according VANET’s criteria security requirements. The underlying network constraints properties from VANET standards have been taken into consideration along with security, reliability other related issues.We also discuss potential forgery attack scenarios scheme. analysis simulation results prove strength adaptability future
