可信的车载软件远程修复框架及实现

摘要

对车载软件安全可信的修复方式进行了研究,提出了一种可信的车载软件远程修复框架.通过Usbkey保证车载终端安全可信,在现有网络条件下搭建可信修复环境保证修复环境可信,通过高效的下载修复模式实现车载终端软件的修复升级,实现了一种车载软件无需特定设备,无需返厂,在现有网络环境下修复升级的框架技术.该框架成本较低且运行安全可靠,具有很高的实用价值.%A method of restoring vehicular software security and credibly is studied, and a kind of reliable car repair software remote framework is put forward. Through the Usbkey guarantee the safety and the reliability of the vehicular terminal. Build credible guarantee environmental under the existing network condition. The vehicular terminal is repaired through efficient, reliable download and update mode. Vehicular software can be restored or upgraded without special equipment or returning back to the factory. This framework can operating reliably with low cost, and has high practical value.
