嵌入式系统的VxWorks安全性问题研究

Research on the Security Mechanism of Embedded RTOS VxWorks

为解决VxWorks系统的安全问题,在分析现有嵌入式安全操作系统构建原理及技术的基础上提出一种适用于VxWorks的安全机制——VxWorks安全内核。该安全内核实现了安全标记以及基于多策略的强制访问控制等安全机制。实现及测试表明该内核安全并且有效。

Based on the analysis of construct theory and technology of existing embedded security operating systems, a security mechanism fit for VxWorks--VxWorks Security Kernel--is put forward. This security kernel implements security tag and MAC（Mandatory Access Control） based on multi-strategies. Test results prove that the security kernel is secure and effective.
