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. The operating system incorporates Formal Verification to ensure that programs perform precisely as intended. 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 kernel/user modules across different layers of abstraction. CertiKOS has 11 repositories available. Follow their code on GitHub.

As another example, CertiKOS adopts a compositional approach for building certified concurrent OS kernels. The researchers have successfully developed a

In Proc. 2016 USENIX Symposium on Operating Systems Design and Implementation (OSDI'16), Savannah, GA, pages 653-669, November 2016.

version of CertiKOS handles the delegation only of CPU cores, RAM, disk, and network I/O. CertiKOS offers privacy guarantees for each of these types of delegated resources. Through hardware-based virtualization [3, 1], CertiKOS also supports transparent iso-lation and resource management, supporting legacy OSes as clients.

We’ve got the best views in the world, live music, Mexican cuisine, bean bags, hammocks, cocktails and beer.

Scientists believe this could lead to a new generation of reliable and secure systems software. 14/11/2016 CertiKOS’s resource ownership records by reassigning ownership of speciﬁc resources to the client. For example, when the manage-ment software starts a hosted client, it might use the CertiKOS man-agement interface to assign a particular set of CPU cores, a particu- 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, 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)".

Jan 05, 2018 · CertiKOS – This is what the IOT should be January 5, 2018 robertmcgrath 4 Comments Now and again I have criticized the software architecture of contemporary consumer electronics , including mobile devices , home automation, and the Internet of Things . 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 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. Check out our video highlighting the research behind the development. CREATE2 Audit Tool Oct 14, 2015 · In contrast, there are some others who suggested the use of CertiKOS, A Certified Kernel for Secure Cloud Computing. CertiKOS is a new architecture which is believed to counter information leakage Nov 22, 2019 · The CertiK Chain will run on CertiKOS, the world’s only fully certified, concurrent OS kernel and hypervisor, which was originally developed by the FLINT Group at Yale University. Additionally, the CVM will be able to run smart contracts developed in the functional programming language, DeepSEA, which has received grants from The Ethereum Nov 06, 2020 · CertiK aims to provide a secure platform where blockchain infrastructure and decentralized applications can be developed. Its ecosystem consists of security layers that exist below the blockchain level, including the DeepSEA compiler, the CertiK Virtual Machine (CVM), and CertiKOS.

A key part of the mission is to engage with industry, learning about adoption obstacles, educating practitioners about how to apply these techniques, and even launching pilot collaborations with specific … CertiKOS represents an effort to apply recent advances in certified software design to a ground-up design of a modular and evolvable certified kernel. Through machine-checkable proof certificates and runtime monitoring, CertiKOS aims to offer users the assurance of correct and leak-free execution of their cloud services. "CertiKOS demonstrates that it is feasible and practical to build verified software that additionally provides evidence — through machine-checkable mathematical proof — that it is functionally correct," says Anindya Banerjee, program director at the U.S. National Science Foundation, which funded the effort.
