It supports Javascript, Micropython, and provides graphical development tools, which can effectively improve development efficiency and reduce development costs, and help customers develop stable, reliable, safe and easy-to-use IoT applications.
OneOS follows Apache license version 2.0, which can be used by individual and enterprise customers in commercial products without publishing the source code and without potential commercial risks. CMIG Internet of Things Ltd. will uphold an open and cooperative attitude to provide customers with a stable system applicable to various IoT scenarios.
OneOS operating system adopts layered architecture design, and the main body consists of driver, kernel, components, and security framework. Through code modularization design, the system is highly scalable and can be flexibly trimmed in conjunction with vertical industry applications. OneOS kernel adopts minimalist design ideas, combining excellent real-time response characteristics with reduced resource overhead, supporting multi-task management scheduling, and providing a wealth of IPC strategies, such as signals, mutexes, message queues, mailboxes and so on, to provide an efficient and reliable RTOS kernel support.
"The kernel is the most core and important part of the operating system, and OneOS uses a preemptible real-time lightweight kernel. On version 2.0, we have implemented efficient task management and scheduling, task synchronization and communication. Multiple memory allocation algorithms are supported to adapt to different application scenarios. On version 3.0, the kernel features are further enriched. "Li Meng talked about.
First, it supports symmetric multiprocessor platform to help advanced applications improve operation efficiency; it supports CPU affinity model to improve task execution efficiency and avoid CPU context switching, which wastes unnecessary performance; it supports MPU isolation protection to realize the isolation of kernel-state access space and user-state access space, key data area tampering prohibition, code segment protection, and to improve the security and reliability of the system; Added dimensionable and measurable functions, such as IPC tracking, interrupt detection, task trajectory tracking, partner monitoring, etc., to help developers detect system status and quickly analyze problems.
As a new type of national critical infrastructure, most of the data in the system are real-time sensory data in specific application scenarios, and there is no lack of sensitive data in nationally important industries, and data security in the IoT system is an important foundation for the healthy development of IoT. In terms of data collection and data transmission security, perception layer node devices are usually simple in structure and very limited in resources, and cannot support traditional complex security functions. For this reason, OneOS has developed a smaller and faster encryption suite and a secure transmission protocol stack in response to the new features and requirements of IoT data security, providing comprehensive data security protection means for IoT terminals.
First of all, in terms of terminal data protection, OneOS security team researched and developed its own lightweight domestic commercial cryptography SM series algorithm suite, the state secret SM series algorithms are independently designed by our country, and are recognized as general algorithms by the State Cryptography Bureau. At the same time for the characteristics of IoT terminal small resources for the special optimization design, greatly reducing the suite itself on the terminal resource occupation, in the same hardware environment, OneOS national cryptographic algorithm suite resource occupation can be reduced by 34%, while the encryption efficiency can be increased by 30%, greatly reducing the pressure on the resources of the terminal equipment, can provide data protection for a wider range of devices.
Meanwhile, OneOS kernel security and system security have been evaluated by China Network Security Review Technology and Certification Center, and it has obtained the first IT product information security classification EAL4+ certification in the field of domestic IoT operating system, which fills the blank of domestic IoT real-time operating system security technology standard.
China Mobile OneOS has high real-time, high security and high reliability characteristics, realizes independent control of key underlying core technologies, and is of great significance to make up for the short boards of China's industrial development and ensure the security and stability of the industrial chain.
