一种机载高安全高可靠数据存储模块的设计
|
摘要
针对综合化、模块化航空电子系统架构中现场可更换模块的设计特点,讨论了一种机载高安全、高可靠的大容量Nand-Flash数据存储模块在符合ARINC653标准的分区操作系统中的设计方法,具有Flash驱动层、Flash管理层、文件系统层架构。通过采用应急关键数据销毁的方式保障系统的高安全性,通过采用坏块管理、损耗均衡以及可信恢复性文件系统的方式保障系统的高可靠性。对数据存储模块进行了不同层级、不同文件大小的读写测试,应急毁钥测试和可靠性测试,测试结果表明模块满足设计要求,可以应用于需要高可靠性和高安全性的航空电子领域。
Aiming at the design features of the Line Replaceable Module( LRM) in the Integrated Modular Avionics a method is proposed for the design of a Nand-Flash data storage module with high security high reliability and large capacity with ARINC653 compliant partitioning operating system. It has a three-layer structure including flash driver layer flash management layer and file system layer. The method of emergency key data destruction is used to ensure the high security of the system and the reliability of the system is guaranteed by adopting bad block management wear leveling and trusted restoring file system. Read/write test emergency key data destruction test and reliability test were made to the data storage module at different levels and with different file sizes and the test results show that the module meets the design requirements and can be applied to the field of avionics requiring high reliability and high security.
