초록

무선센서네트워크는 다양한 응용을 가지고 있고 아주 넓은 지역에 배치된다. 특히, 이들 네트워크는 잠재적인 위험을 포함한 환경에 배치됨으로 이에 대한 보안 이슈를 해결하기 위한 많은 노력이 있다. 최근에 무선센서네트워크에서 대칭키암호시스템에 기반한 익명의 사용자 인증과 키동의 기법 (AUAKAS)이 제안되었다. AUAKAS는 가장공격을 포함한 다양한 공격에 안전하다고 주장하였다. 하지만 본 논문은 AUAKAS가 게이트웨이에 등록된 정당한 사용자에 의하여 사용자 가장 공격과 게이트웨이 가장 공격에 취약함을 보인다. 본 논문의 보안 분석은 다양한 새로운 보안 기법의 설계에 있어서 미리 고려할 중요한 특성 분석에 있어서 도움을 줄 수 있을 것이다.

Wireless sensor networks (WSNs) have many applications and are deployed in a wide variety of areas. They are often deployed in potentially adverse or even hostile environment so that there are concerns on security issues in these WSNs. Recently, an anonymous user authentication and key agreement scheme (AUAKAS) was proposed based on symmetric cryptosystem in WSNs. It is claimed in AUAKAS that it assures security against different types of attacks including impersonation attacks. However, this paper shows that AUAKAS does not cope from user impersonation attack and gateway impersonation attack from the legally registered user on the gateway. The security analysis could guide the required features of the security scheme to be satisfied.
