초록

본 논문은 IEEE 802.11i의 4-way 핸드쉐이크 프로토콜을 안전성과 신뢰성의 측면에서 분석한다. 분석을 통해 MIC 오류와 같은 특정한 상황에서 4-way 핸드쉐이크가 정상적으로 수행되지 못하는 것을 보여주고 문제 해결을 위한 수정방안을 제안한다. 또한 4-way 핸드쉐이크 프로토콜보다 안전하고 효율적인 2-way 핸드쉐이크 프로토콜을 제안한다.

Abstract

In this paper, a 4-way Handshake protocol in the IEEE 802.11i is analyzed in terms of both security and reliability. It is shown that the 4-way Handshake protocol breaks down under some conditions due to a MIC (message integrity code) failure, and a solution to fix it is proposed. It is also proposed that a new 2-way Handshake protocol which is more secure and efficient than the 4-way Handshake protocol.
