Abstract

Recently, important information related with smart work such as office and video conference are handled in smart device quite a lot compare with before. Also, execution environment of smart devices is getting developed as open software environment. It brought convenience to download and use any kind of application software. By that, security side of smart devices became vulnerable. This paper will discuss characteristics of smart device security technology based on virtualization that is a mobile device platform with isolated secure execution area based on TEE (Trusted Execution Environment). Also, this paper will suggest an implementation method about safe smart device security platform based on domain separation for application software which can be executed in smart devices. The domain separation based smart device security platform technology in this paper blocks unauthorized access and leakage of sensitive information in device. Also it will be the solution can block transmission and execution of malicious code in various area including variety of IoT devices in internet rather than just smart devices.

최근 들어, 스마트 단말에서 오피스, 화상회의 등 스마트워크 업무와 관련된 중요한 정보들을 다루는 경우가 많아졌다. 또한 스마트 단말의 실행환경이 공개 소프트웨어 환경 위주로 발전하면서, 사용자들이 임의의 응용소프트웨어를 다운받아 사용하는 것이 용이하게 됨에 따라, 스마트 단말이 보안적 측면에서 취약하게 되었다. 본 논문에서는 TEE(Trusted Execution Environment) 기반의 격리된 안전실행환경 영역을 가지는 모바일 단말 플랫폼인 가상화 기반 스마트 단말 보안 기술의 특징을 알아본다. 또한, 본 논문에서는 스마트 단말에서 실행되는 응용프로그램을 위한 도메인 분리 기반의 안전한 스마트 단말 보안 플랫폼에 대한 구현방법을 제안한다. 본 논문의 도메인 분리 기반 스마트 단말 보안 플랫폼 기술은 단말내의 민감 정보 유출과 비인가 접근을 차단한다. 또한 이 기술은 스마트 단말뿐만 아니라 인터넷 상의 다양한 IoT를 포함한 다양한 기기에서 악성코드의 실행과 전파를 막을 수 있는 솔루션이 될 것이다.
