Vehicular communication networking can provide well-suited traffic messages, emergency warning messages and infotainment dissemination, and improve driving condition for drivers. The authentication of these information is particularly important in VANET since the wrong traffic information may result in traffic accident and traffic jam. And VANET requires short verifying delay to response messages. To identify invalid messages and reduce verifying delay, a lot of schemes have been proposed to verify the information of VANET by batch verification technique. Recently, Lee et al.' proposed an improved authentication scheme with batch verification based on bilinear pairing to make VANET more secure, efficient, and more suitable for practical use.
