Intelligent Vehicle means vehicles communication with everything such as, in-vehicle, vehicle-to-device, vehicle to vehicle communication, vehicle to roadside unit (RSU), etc. In short, we can say that intelligent vehicle is a system that provides communication environment between vehicles to everything (objects). Due to everything communicating to vehicles, it generates a large amount of data. Data generation is fine with this technology but we need to make sure that these data are safely and securely communicated with their designated destination (right device or users). Privacy of users is another big challenge in intelligent vehicle system. In this article, we discuss the challenges of automotive security in hardware and software, and propose a security architecture for automotive security and also mention future research challenges in automotive cyber security. This paper presents a discussion on Internet oriented application specific secure automotive technology, services, visual aspect and challenges for intelligent vehicles in both academic and industry.
