CUBE is a security platform for autonomous vehicles based on blockchain technology. Autonomous cars rely heavily on wireless communication techniques, such as vehicle-to-vehicle, navigation route information, GPS, and other driving data. Autonomous cars continuously communicate with various sites to remotely monitor their internal and outside states. These various network accesses increase the risk of malicious attacks on autonomous vehicles. Cube solves the problem of these autonomous vehicles’ security by using blockchain technologies, AI-based deep learning and quantum hash cryptography. In the future, the $770 billion autonomous automotive market will see Cube as the first user of blockchain-based security. We will provide an autonomous vehicle security platform to companies such as automotive manufacturers, and related firms, such as Google and Uber.
