Using Adaptive Zero-Knowledge Authentication Protocol in VANET Automotive Network

One of the most important components intelligent transportation systems (ITS) is automotive self-organizing VANET network (vehicular ad hoc network). Its nodes are vehicles with specialized onboard units (OBU) installed on them. Such a can be subject to various attacks. To reduce effectiveness number attacks VANET, it advisable use authentication protocols. Well-known protocols support security policy full trust in roadside unit (RSU) base stations. The disadvantage these ability RSU track route vehicle. This leads violation privacy and anonymity vehicle’s owner. eliminate this drawback, article proposes an adaptive protocol. An advantage protocol provision high imitation resistance without using symmetric asymmetric ciphers. result has been achieved by zero-knowledge A scheme for adapting parameters depending intensity user’s traffic developed proposed scientific novelty solution time spent changing execution algorithm reducing modular exponentiation operations when calculating true “distorted” digests prover verifying correctness responses, as well responses. Authentication, before, takes place one round bit depth modulus used evaluate protocol, model was implemented NS-2. obtained research results have shown that adaptation conditions increased density road makes possible increase volume data exchange between OBU level confidentiality. In addition, mechanism authority owner provided services developed. As implementation mechanism, vehicle registration sites (VRS) calculate public key encryption provide necessary
