LX-OS, the Nexus Operating System (OS) will initially run on micro-satellites and IoT (Internet of Things) devices, which generally have weak security models. LX-OS uses Signature Chains to authenticate the runtime memory, file systems, and other system servers. It will operate on a distributed filesystem, solving the problem of moving the entire App & OS state from one device to another. LX-OS is built on the seL4 micro-kernel, which when combined with Nexus, can resist attacks from malware, backdoors, and other common vulnerabilities. seL4 is part of an ecosystem supporting active use in various domains including automotive, aviation, infrastructure, medical and defence.
The Lower-Level Library (LLL) is the backbone of LX-OS. The LLL contains three main components: Cryptography (LLC), Database (LLD), and Protocol (LLP). The LLC is a collection of useful cryptographic functions including Quantum Resistant algorithms, the LLD runs in constant time O(1) handling large datasets without losing performance, while the LLP allows the rapid development and deployment of high performance binary or hyper-text protocols.
