Abstract

In wireless sensor networks, a compromised sensor node can inject false data during data aggregation. Existing solutions of securing data aggregation require high communication cost in securing data aggregation. In this paper, we propose a monitoring-based secure data aggregation protocol that minimizes communication cost of identifying the location of false data injection attacks. The main idea is that when monitoring nodes find an injected false data, their reporting messages along with Message Authentication Codes (MACs) are summarized in a single message before sending it to the Base Station (BS). Then the BS identifies the attacking node. The simulation shows that energy consumption of the proposed protocol with short and normal concatenations of MACs are 45% and 36% lower than that of an existing protocol, respectively.

무선 센서 네트워크에서 compromised node는 데이터 병합과정에서 허위 데이터를 삽입할 수 있다. 데이터 병합의 보안성을 위한 기존 접근 방법들은 높은 연산 부하를 요구한다. 따라서 본 논문에서는 허위 데이터 삽입 공격 발생 지점을 식별하는데 소요되는 통신 부하를 최소화하는 모니터링 기반 시큐어 데이터 병합 프로토콜을 제안한다. 제안된 프로토콜은 허위 데이터 삽입이 탐지되면 모니터링을 수행하고 있던 노드들의 MAC(Message Authentication Code)을 하나의 메시지로 요약하고 이를 BS(Base Station)로 전송하는 방법을 사용하며, BS는 이를 통해 공격 노드를 식별한다. 실험 결과는 제안된 프로토콜이 MAC들의 짧은 연결과 보통 연결을 사용하는 경우, 기존 연구에 비해 각각 45% 및 36% 적은 에너지를 사용하는 것으로 나타났다.
