[SW Security] OBFSCURO: A Commodity Obfuscation Engine on Intel SGX, Network and Distributed System Security Symposium (NDSS), Feb. 2019

OBFSCURO: A Commodity Obfuscation Engine on Intel SGX, Network and Distributed System Security Symposium (NDSS), Feb. 2019

Adil Ahmad, Byunggill Joe, Yuan Xiao, Yinqian Zhang, Insik Shin, Byoungyoung Lee

본 논문은 Trusted Computing 환경인 SGX 위에서 이론적으로 안전한 프로그램 obfuscation 기술을 제안한다. 프로그램의 데이터플로우, 컨트롤플로우가 모두 Oblivious RAM을 통하여 동작하므로, 최근 알려진 각종 사이드체널 공격 (페이지폴트 기반, 캐쉬 기반, 브랜치 프리딕터 기반 등)에도 안전하다.
