Enabling trustworthy Vehicle to Vehicle (V2V) communication given the wireless medium and the highly dynamic nature of the vehicular environment is a hard challenge.Eavesdropping and signal jamming in such highly dynamic environment is a real problem.This paper proposes a nature inspired multidimensional Moving-Target Defense (MTD) that employs real time spatiotemporal diversity to obfuscate wireless signals against attacker reach.In space: the mechanism manipulates the wireless transmission pattern and configuration to confuse eavesdroppers.In Time: we manipulate the transmission payload, by intentionally injecting some fake data into the real transmission.Further, the mechanism changes the data transmission granularity over time from fine to coarse grained data chunks.As a case study, we assumed the direct transmission model across dynamic multi-paths relayed communication via vehicles traveling on a multi-lane road.The system is evaluated based
