Abstract

PKMv2 security protocol was adopted by the WiMax2 mobile internet communication standard. A base station and a mobile station protect communication data using key based encryption according to the PKMv2 protocol. Consequently, each development of a base station and/or mobile station includes implement of the PKMv2 protocol, and the station must qualifies various interoperable tests. Furthermore, communication bandwidth of the station can be limited by the encryption module when the station implemented based on a low-performance processor. Thus, a correspondence measurement of the encryption module must be carried on the target processor. In this paper, we implement a testbed which affords throughput measurement as well as the interoperable tests by PKMv2.

모바일 인터넷 통신 표준인 WiMax2는 PKMv2 프로토콜을 이용한다. PKMv2는 키에 기반한 암호화를 사용하여 통신 기지국과 단말간의 데이터를 보호한다. 따라서 WiMax2 단말 또는 기지국을 개발하는 경우 PKMv2 프로토콜을 구현하여야만 하며, 상호 동작에 대한 적합성 테스트를 통과하여야 한다. 또한 저성능 프로세서를 이용하는 단말의 경우 암호화 모듈의 처리 성능이 WiMax2 통신의 데이터 처리 능력에 병목이 될 수 있으므로 해당 프로세서에서의 암호화 모듈 처리 성능의 적절성을 측정하여야 한다. 본 논문은 이러한 경우에 사용할 수 있는 WiMax2 PKMv2에 따르는 동작성 시험 및 성능 측정 테스트베드를 구현하였다.
