스마트 카드를 사용한 검증자 없는 사용자 인증 및 접근 제어 방법: Chen-Yeh 방법의 개선 = A Verifier-free Scheme for User Authentication and Access Control Using Smart Cards: Improvement of Chen-Yeh`s Method

다국어 초록 (Multilingual Abstract)

User authentication and access control are two important components in high security applications. Recently, Chen and Yeh proposed a method to integrate both of them seamlessly. However, Chen-Yeh`s scheme is vulnerable to a stolen verifier attack, since it maintains a smart card identifier table in a remote server. Therefore, this paper modifies Chen-Yeh`s scheme and propose a new integrated authentication and access control scheme that is resilient to the stolen verifier attack while inheriting all the merits of Chen-Yeh`s scheme. Security analysis shows that the proposed scheme withstands well-known security attacks and exhibits many good features.
