Route Plan Exchange Scheme Based on Block Chain

Route Plan describes recommended movement of vessels. It consists of waypoints, and each waypoint demonstrates expected arrival/departure times, angle, and direction. The importance of route plan is become more important as appearance of autonomous ship. To achieve safe and smart voyage, integrity of route plan is very important. To avoid forgery and temper of route plan, and clarify who is responsible, digital signature is one of reliable solution. In this study, we suggest route plan management scheme which demonstrates how to manage digital signature of route plan based on block chain.
