Access Rights

The Windows Embedded operating system (OS) adopts a discretionary access control (DAC)-based policy, but underlying vulnerabilities exist because of external hacker attacks and other factors. In this study, we propose a system that improves the security of the Windows Embedded OS by applying a mandatory access control (MAC) policy in which the access rights of objects, such as files and folders, and subjects’ privileges, such as processes, are compared. We conducted access control tests to verify whether the proposed system could avoid the vulnerabilities of DAC-based systems. Our results indicate that the existing DAC-based security systems could be neutralized if a principal's security policy is removed. However, in the proposed MAC-based Windows Embedded OS, even if the clearance and category values of a subject’s files are given the highest rating, all accesses are automatically denied. Therefore, the execution of all files that were not previously registered on the whitelist was denied, proving that security was improved relative to DAC-based systems.

This paper describes a system; CODESSEAL can provide protection and evaluation to system software. CODESSEAL was designed to protect embedded systems with sufficient expertise and resources to capture attack equipment and manipulator, not only to protect software but also to protect hardware. By using the reconfigurable hardware allows CODESSEAL to provide confidentiality, integrity of security services and a platform-independent program flow without having to redesign the processor. System uses software and data protection technology and designs cycle simulation methods for data analysis. Experimental results show that the protected instructions and data with a high level of safety can be realized a low, which in most cases the performance loss can be reduced to below 10%, so the research of software protection methods of the embedded operating system of hardware compiler has important practical significance.

The locomotive coupling came from the development of heavy-haul transportation in railway. Considering the insufficiencies of cable and radio in locomotive coupling at present, a new method of locomotive coupling is presented in this paper. The overall design of system scheme is provided based on WLAN. The system feasibility is analyzed and verified by using OPNET Modeler. The hardware structure of coupling transmission device and development process of embedded operating system are described briefly. Finally, taking measures guarantees the system reliability of data transmission.

This paper describes the design and implementation of an ARM based embedded operating system micro kernel developed on Linux platform with GNU tool chain in technical details, including the three-layer architecture of the kernel (boot layer, core layer and task layer), multi-task schedule (priority for real-time and round-robin for time-sharing), IRQ handler, SWI handler, system calls, and inter-task communication based on which the micro-kernel architecture is constructed. On the foundation of this micro kernel, more components essential to a practical operating system, such as file system and TCP/IP processing, can be added in order to form a real and practical multi-task micro-kernel embedded operating system.
