SMACK is both a modular software verification toolchain and a self-contained software verifier. It can be used to verify the assertions in its input programs. In its default mode, assertions are verified up to a given bound on loop iterations and recursion depth; it contains experimental support...

SGXRay: SGX 앱을 위한 취약점 탐지 자동화 Intel SGX는 하드웨어 기반 메모리 암호화를 통해 격리된 애플리케이션 로직과 민감한 데이터를 보호합니다. 이러한 하드웨어 기반 보안 메커니즘을 사용하려면 메모리 사용에 대한 엄격한 프로그래밍 모델이 필요하며, 보호 영역 경계 안팎에는 복잡한 API가 있습니다. 보호 영역 개발자는 특히 신뢰할 수 있는 경계를 넘어 흐르는 데이터를 처리할 때 보호 영역 보안을 보장하기 위해 신중한 프로그래밍 방법을 적용해야 합니다. 신뢰할 수 있는 경계 위반은 메모리 손상을 일으킬 수 있으...
