- W2023165830 abstract "안드로이드 파일시스템은 임의적 접근제어 방식을 사용하여 시스템의 자원에 접근할 수 있는 오픈 시스템이기 때문에 상대적으로 저장장치에 대한 제어가 필요하다. 이러한 특성으로 인해 안드로이드의 VDC를 통해서 접근제어를 하는 경우 안드로이드가 VDC 기능을 제공하는 경우에만 가능하다는 문제점이 있다. 이를 개선하는 방법으로는 VDC의 기능을 시스템 콜(system call)을 통하여 직접 구현함으로써 OS와는 별도로 연동 모듈을 만들어 저장장치 제어기능을 추가하여야 한다. 본 논문에서는 일반적인 저장장치의 마운트 시스템에 대하여 VDC 기능을 이용하여 사용자에 대한 접근을 제어하는 방법을 제안하였다. SD, UMS 와 같은 저장장치에 대한 접근제어를 마운트 방식에 의하여 구현하였고 제안된 기법이 제어가 설정된 저장장치에 파일을 복사/저장하려면 쓰기가 금지되어 제어가 수행됨을 실험을 통하여 검증하였다. 【Android file system is vulnerable to the external access of system resources via its arbitrary access mode and need user's control for SD and UMS medias due to its open architecture. In response to the device control, there is a drawback that its controlability is valid only in the case of embedded linux kernel with VDC function. Hence the solution is to directly implement VDC through system call, with another security module for device storage than system module being added to android system. In this paper the new method of android storage access control for personal information is proposed via VDC for mount system of storage. The access method for SD and UMS were implemented using VDC and mount mechanism. This access control system has been designed to control the granted users in kernel level if files are flowed out by copying. As a result, it was proved through testing that the access control system has exactly detected the write access operation.】" @default.
