CYBERSECURITY IN THE AGE OF V2X With the advent of digitalization and advanced technologies, the vehicles are becoming more intelligent and less reliant on human operation. From infotainment to autonomous driving, we have seen things getting evolved over the time. But have you ever imagined a technology that allows vehicles to communicate with each other, its surroundings and pedestrians? V2X is the practical implementation of such imagination and result of years of development and research. This vehicular communication technology is designed to improve traffic efficiency by preventing road accidents, providing warnings for upcoming traffic congestion and proposing alternative routes.
