Abstract
B-MAC 프로토콜은 WSN을 위해 설계된 적용적인 프리엠블 샘플링 기법을 사용하는 잘 알려진 MAC 프로토콜이다. 이 논문에서 우리는 B-MAC 보안 취약성에 관해 살펴보았으며, 슬립 거부 공격의 취약성과 재연공격 문제에 따른 B-MAC 프로토콜의 각 단계에 소비되는 전력을 분석하였다. 연구결과로부터 일반적인 B-MAC 통신을 위한 신뢰성, 효율성, 보안을 제공하는 전력에 효율적인 인증 기법의 필요성에 대해 고찰하였다. 이 연구는 B-MAC에서 전력소비와 가능한 서비스 거부 공격 취약점에 대한 사례연구이다. Berkley Media Access Control (B-MAC) protocol is one of the well-known MAC protocols, which uses adaptive preamble sampling scheme and is designed for wireless sensor networks (WSN). In this paper, we are reviewed about security vulnerability in B-MAC, and analyzed the power which is consumed at each stage of B-MAC protocol according to vulnerability of denial of sleep(DoS) and replay problem. From our analytical results, it can be considered the need of power efficient authentication scheme which provides the reliability, efficiency, and security for a general B-MAC communication. This is the case study of possible DoS vulnerability and its power consumption in B-MAC.
