초록

인지무선네트워크(Cognitive Radio Networks, CRNs)는 네트워크 환경을 인지하고 적응적으로 운용할 수 있는 지능형 무선 네트워킹을 제공하기 위한 기술로 인지되고 있다. CRN은 FCC(Federal Communications Commission)의 최근 정책으로 인해 비인가된 사용자가 네트워크의 주사용자를 방해하지 않는 한 유휴 스펙트럼을 활용할 수 있도록 허락하는 기술이다. 그러므로 CRNs의 보안 특성은 다른 네트워크와 달라야만 한다. 본 논문의 목적은 Tsai등의 위임기반 인증 프로토콜(TDAP)로부터 CRN상의 비인가된 사용자를 위한 보안의 특성을 추출함으로서 새로운 위임기반 인증 프로토콜(NDAP)을 제안하는데 있다. 먼저 TDAP에 대한 보안분석을 제시하고 비인가 사용자 인증을 위한 프로토콜 설계 목표를 설정한다. 그런 후 TDAP에 대한 보안 해결책과 CRNs를 위한 새로운 프로토콜로서 NDAP을 제안한다. 본 논문에서 제안한 NDAP은 CRNs과 다양한 융합응용의 보안 기반 구조로 활용될 수 있을 것이다.

Cognitive radio networks (CRNs) offer the promise of intelligent radios that can learn from and adapt to their environment. CRN permits unlicensed users to utilize the idle spectrum as long as it does not introduce interference to the primary users due to the Federal Communications Commission's recent regulatory policies. Thereby, the security aspects in CRNs should be different with the other networks. The purpose of this paper is to devise a new delegation-based authentication protocol (NDAP) by extracting out the security aspects for unlicensed user authentication over CRNs from Tsai et al's delegation-based authentication protocol (TDAP). First of all, we will provide security analyses on the TDAP and set design goal for unlicensed user authentication. Then, we will propose a NDAP as a remedy mechanism for the TDAP and a new protocol for CRNs. The NDAP could be used as a security building block for the CRNs and various convergence applications.
