【摘要】：随着移动智能终端设备的迅速发展与普及应用,移动智能终端已经成为人们学习、工作和生活的不可或缺的一部分。关于终端设备的安全性问题越来越受到个人与企业等关注。现今终端设备越来越多的涉及到个人隐私和商业机密,与此同时终端设备也受到各种安全威胁。伴随着互联网的发展,终端设备作为移动互联网时代的信息载体,如何防止信息泄露是人们都在关心的问题。因此开展对移动智能终端设备的信息安全保护研究具有迫切性和重要性。本文基于可信计算的嵌入式系统移动终端设计就是为新的信息安全形势来进行开发设计的。本文主要通过完成安卓系统的移植工作,并在此基础上实现TPM的集成工作。硬件方面主要完成了原理图设计、PCB设计、焊接调试和结构设计,软件方面主要完成了 bootloader、Linux内核、文件系统和Android等移植。最后对嵌入式系统完成之后进行基于TPM的可信测试。嵌入式系统由bootloader、Linux内核、文件系统等构成。其中主要是基于板级的启动加载程序bootloader,Linux内核部分的TPM的驱动程序开发设计,Android系统和上层应用程序文件加解密系统。本文研究的嵌入式可信计算移动终端采用的是基于ARM Cortex-A8架构的三星S5PV210芯片作为主处理器和ATMEL公司TPM芯片AT97SC3204T-28A2作为可信模块。软件方面,选择了基于Linux3.1.10内核的android 4.4_rl.2作为嵌入式操作系统。本课题在研究过程中,进行了大量测试,完了成从bootloader,Linux3.1.10,Android和文件系统的定制与移植,实现了对重要信息的加解密及对系统的安全防护。经测试,本套系统达到预计设计要求,对现在的智能移动终端安全性问题有较高的参考价值。
[Abstract]:With the rapid development and popularization of mobile intelligent terminal devices, mobile intelligent terminals have become people's learning. Work and life is an integral part of life. The security of terminal equipment is increasingly concerned by individuals and businesses. Nowadays, terminal devices are increasingly involved in personal privacy and trade secrets. At the same time, terminal equipment is also subject to various security threats. With the development of the Internet, terminal equipment is used as the information carrier in the era of mobile Internet. How to prevent information leakage is a problem that people are concerned about. Therefore, it is urgent and important to study the information security protection of mobile intelligent terminal devices. This paper introduces the embedded system mobile terminal device based on trusted computing. This paper is designed for the development of the new information security situation. On this basis, the integration work of TPM is realized. In hardware, the schematic design, welding debugging and structure design are completed, and the bootloader Linux kernel is mainly completed in software. The file system and Android are transplanted. Finally, the trusted test based on TPM is carried out after the embedded system is finished. The embedded system is composed of bootloader kernel, Linux kernel and so on. The design of TPM driver based on the bootloader kernel part of the bootloader Linux kernel and the encryption and decryption system of the upper application files. The embedded trusted Computing studied in this paper. The mobile terminal uses Samsung S5PV210 chip based on ARM Cortex-A8 architecture as the main processor and ATMEL company TPM chip AT97SC3204T-28A2 as the trusted module. Android 4.4rl.2 based on Linux3.1.10 kernel is selected as the embedded operating system. In the course of the research, a lot of tests have been carried out, and the customization and transplantation of the bootloader Linux 3.1.10 and the file system have been finished. It realizes the encryption and decryption of the important information and the security protection of the system. The test results show that the system meets the expected design requirements and has a high reference value for the security problems of the intelligent mobile terminal.
