초록
장거리 무선 표준 LPWAN 표준의 비 대역망 기술인 Lora는 내부 단말 인증 및 무결성 검증에 ABP, OTTA 방식과AES-128 기반 암호 알고리즘(공유키)을 사용한다. Lora는 최근 펌웨어 변조 취약점과 공유키 방식의 암호 알고리즘 구조상MITM 공격 등에 방어가 어려운 문제가 존재한다. 본 연구는 Lora 네트워크에 안전성 강화를 위해 블록체인을 합의 알고리즘(PBFT)을 적용한다. GPS 모듈을 활용하여 노드 그룹을 검색하는 방식으로 인증과 PBFT의 블록체인 생성과정을 수행한다. 성능분석 결과, 새로운 Lora 신뢰 네트워크를 구축하고 합의 알고리즘의 지연 시간이 개선했음을 증명하였다. 본 연구는4차 산업 융합연구로써 향후 Lora 장치의 보안 기술 개선에 도움이 되고자 한다.
Abstract
Lora, a non-band network technology of the long-distance wireless standard LPWAN standard, uses ABP and OTTA methods and AES-128-based encryption algorithm (shared key) for internal terminal authentication and integrity verification. Lora’s recent firmware tampering vulnerability and shared-key encryption algorithm structure make it difficult to defend against MITM attacks. In this study, the consensus algorithm(PBFT) is applied to the Lora network to enhance safety. It performs authentication and PBFT block chain creation by searching for node groups using the GPS module. As a result of the performance analysis, we established a new Lora trust network and proved that the latency of the consensus algorithm was improved. This study is a 4th industry convergence study and is intended to help improve the security technology of Lora devices in the future.
