Towards an IPsec security GeoNet architecture

In order to connect Vehicle Ad-hoc NETworks (VANETs) to the Internet, most of manufactures car consortia and standardization bodies (IEEE 1609, CALM, C2C-CC, and ETSI TC ITS) proposed IPv6 protocol in the VANET protocol stack. The European GeoNet project was founded to investigate how GeoNetworking and IPv6 can be combined together. The GeoNetworking provides geographic address and routing for vehicular communications. In this paper, we identify attacks that can be performed on mechanisms and protocols necessary to run IPv6 over the GeoNetworking layer and propose a secure GeoNet architecture based on the IPsec protocol to prevent most of the threats.
