Description

차량 간 통신 환경에서 블록체인 기반 분산 데이터 저장 시스템 및 방법{Blockchain-based Distributed Data Storage System and Method in Inter-vehicle Communication Environments}Blockchain-based Distributed Data Storage System and Method in Inter-vehicle Communication Environments

본 발명은 차량 간 통신 환경에서 블록체인 기반 분산 데이터 저장 시스템 및 방법에 관한 것으로, 보다 상세하게는 블록체인을 기반으로 각 차량의 데이터 신뢰성을 향상시킬 수 있는 차량 데이터 저장 방법에 관한 것이다.The present invention relates to a blockchain-based distributed data storage system and method in an inter-vehicle communication environment, and more particularly, to a vehicle data storage method capable of improving the data reliability of each vehicle based on the blockchain.

차량 간 통신 기술은 802.11p, LTE, mmWave 등의 무선 신호 전송 및 수신을 위한 통신 기술과 차량 간의 통신 연결망 설정을 위한 라우팅 기술로 구성된다. BSM(Basic Safety Message)은 차량의 속도, 브레이크 상태, 진행방향 등의 데이터로 구성되며, 미국 교통부에서는 차량 간 주행 데이터를 전달할 때 최소 100ms 이하의 주기로 전송해야 한다고 하고 있다. 차량 간 통신에서는 보통 Dedicated Short Range Communication을 이용해 주행 데이터를 전달하며 1홉 거리의 차량들에게 브로드캐스트 한다. 하지만 기존 BSM 브로드캐스트만으로는 차량 간 데이터의 신뢰성을 보장할 수 없으며, 위변조를 방지하기 어렵다. 또한, 비트코인 기술을 이용해 분산 데이터 저장을 할 경우 블록 하나당 저장 가능한 크기가 83바이트에 불과하여 50~100바이트의 BSM 데이터를 저장하기 어렵다는 문제점을 안고있다.The vehicle-to-vehicle communication technology consists of a communication technology for transmitting and receiving wireless signals such as 802.11p, LTE, and mmWave, and a routing technology for establishing a communication connection network between vehicles. BSM (Basic Safety Message) consists of data such as vehicle speed, brake status, and direction of travel, and the U.S. Department of Transportation says that when transmitting driving data between vehicles, it should be transmitted at a cycle of at least 100ms. In vehicle-to-vehicle communication, driving data is usually transmitted using Dedicated Short Range Communication and broadcast to vehicles within one hop distance. However, the existing BSM broadcast alone cannot guarantee the reliability of inter-vehicle data, and it is difficult to prevent forgery. In addition, when distributed data is stored using Bitcoin technology, it is difficult to store 50 to 100 bytes of BSM data because the size that can be stored per block is only 83 bytes.

이에 따라, 차량 간 주행 데이터의 보안성과 무결성을 보장하고, 다른 악의적인 차량으로부터 발생할 수 있는 공격이나 네트워크 단절로 인한 문제를 방지하고 다른 차량에 주행 데이터를 분산 저장할 수 있는 기술이 필요한 실정이다.Accordingly, there is a need for a technology that can ensure the security and integrity of driving data between vehicles, prevent problems due to attacks or network disconnection that may occur from other malicious vehicles, and distribute and store driving data in other vehicles.

이에 본 발명은 상기와 같은 종래의 문제점을 해소하기 위해 제안된 것으로, 차량 간 주행 데이터의 보안성과 무결성을 보장하고, 다른 악의적인 차량으로부터 발생할 수 있는 공격이나 네트워크 단절로 인한 문제를 방지하고 다른 차량에 주행 데이터를 분산 저장할 수 있는 방법을 제공하는 것을 목적으로 한다.Accordingly, the present invention has been proposed to solve the problems of the related art as described above, to ensure the security and integrity of driving data between vehicles, to prevent problems due to attacks or network disconnection that may occur from other malicious vehicles, and to prevent other vehicles The purpose of the present invention is to provide a method for distributing and storing driving data in
