CertiKOS: A Certified Kernel for Secure Cloud Computing. Liang Gu, Alexander Vaynberg, Bryan Ford, Zhong Shao, and David Costanzo. In Proc.

4.3 CertiKOS for CertiK Chain. CertiKOS is a certified, concurrent operating system kernel originally developed at Yale University, receiving international acclaim as the world's first "hacker-resistant" OS kernel. It is written in C and formally verified using the Coq interactive proof assistant.

The mission of the CertiK Foundation is to leverage better technology to create a more trustworthy blockchain ecosystem for all.

It is an interesting target for verification---short and subtle, involving both liveness and safety properties. We implemented and verified the MCS Lock algorithm as part of the CertiKOS kernel, showing that the C/assembly implementation contextually refines atomic specifications of the acquire and release lock methods. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. CertiKOS presents a layered approach for verifying the correctness of an OS kernel with a mix of C and assembly code [40]. CertiKOS adapts CompCert [58], a verified C com-piler, to both reason about assembly code directly, as well as prove properties about C code and propagate guarantees to the assembly level. CertiKOS thus verifies the entire Global Index A A [abbreviation, in mcertikos.clib.CDataTypes] aaddr [definition, in compcert.backend.ValueAnalysis] aaddressing [definition, in compcert.backend Oct 16, 2020 · CertiKOS for CertiK Chain CertiKOS is a certified, concurrent operating system kernel (the core of any OS) and hypervisor developed at Yale University, receiving international acclaim as the world Nov 15, 2019 · CertiKOS. CertiKOS is the world’s first operating system that runs on multi-core processors and shields against cyber attacks — a milestone that could lead to a new generation of reliable and secure systems software.

Instructions for Concurrent CertiKOS Artifact. This document contains the instructions for compiling and evaluating the concurrent CertiKOS artifact built on our "Certified Concurrent Abstraction Layers (CCAL)". We intend to clarify in this document every detail that people may need to consider. CertiKOS. Functionally-Correct OS Kernel ‍CertiKOS is the world’s first fully certified multi-core OS kernel assured to be safe, functionally correct, and hacker-resistant.

Complete formal verification of a non-trivial concurrent OS kernel is widely considered a grand challenge. We present a novel compositional approach for building certified concurrent OS kernels. Concurrency allows interleaved execution of … CertiKOS is using a DSL approach if it's same as paper I'm remembering. They design languages or proving techniques ideal to the type of thing they're working on: memory management, I/O, etc. They prove each individual component as easily as they can. Then they have some way of modeling the system as a whole and/or integrating those.

CertiKOS uses contextual refinement over the 2 Jun 2020 It was originally inspired by research on verified systems, and contains some of the lessons learnt from developing the CertiKOS operating 2017年11月22日 CertiKOS具有极高的安全性和可靠性，采用了模块分层验证法（modular layered verification methods），拥有并发性，可同时在多个CPU内核上 CertiKOS layers were extended with formal resource models. New thread objects were added as basic building blocks and used to model the hardware and The system relies on a secure/verified environment, from the microkernel level ( e.g., CertiKOS, http://flint.cs.yale.edu/certikos/) to the full OS, providing the 1 Oct 2019 We have been studying CertiKOS for many years at Yale University.

Professional Developement Center Certikos Nov 15, 2016 · The CertiKOS operating system is different in that it supports concurrency, which means that it enables multiple sequences of programmed instructions, known as 'threads', to run simultaneously on CertiKOS: A Breakthrough toward Hacker-Resistant Operating Systems Zhong Shao Yale University January 25, 2018 Acknowledgement: Ronghui Gu, Newman Wu, Hao Chen, Jieung Kim, Jeremie Koenig, Vilhelm Sjoberg, Mengqi Liu, Lionel Rieg, Quentin Carbonneaux, Unsung Lee, Jiyong Shin, David Costanzo, compiler.19 Thus, under CertiKOS, an otherwise prohibitive verification task can be decomposed into many simple and easily automatable ones, and proven global properties can be propagated down to the assembly level. Using CertiKOS, we have successfully developed a fully certi-fied concurrent OS kernel mC2 in the Coq proof assistant. The CertiKOS is the world's first fully certified multi-core OS kernel, assured to be safe, functionally correct, and hacker-resistant. The operating system incorporates Formal Verification to ensure that programs perform as intended. The Operating System (OS) will run multiple threads simultaneously, useful when running on modern multi-core machines. In order to manage such a large veriﬁcation effort, the CertiKOS team developed a methodology known as certiﬁed (concurrent) abstraction layers, as well as a set of libraries and theorems to support it.
