摘要
针对普通嵌入式设备引导过程中的安全隐患,在分析Marvell公司的PXA微处理器的基本特性和结构的基础上,借鉴可信计算思想,加入可信密码模块(trusted cryptography module,TCM)和可恢复性机制,设计了一种基于PXA微处理器的可信引导方案,并将其应用到移动警务终端。该方案确保了设备在启动过程中的完整性,有效地防止了程序被篡改,在一定程度上提升了设备运行的安全性和可靠性。
In view of the potential safety hazard in the bootstrap process of common embedded devices,and on the basis of the analysis of the basic features and structure of Marvell PXA microprocessor,a trusted bootstrap scheme based on PXA microprocessor is designed by adding a trusted cryptography module and recoverability mechanism,and is applied to mobile police terminals. This design ensures that the integrity of equipments in starting procedure,effectively prevents programs from being tampering with,and to a certain extent promotes the security and reliability of equipment operation.
