可信软件设计实验环境搭建

非常坑,之前尝试过使用 yum 直接安装 trousers,会出现 TPM_E_NOAUTH 的问题,现在使用 trousers-0.3.15 进行编译后能够正常进行实验,目前还不清楚是什么包的问题导致的,因此要确保系统是全新的。

基础环境准备

实验环境基于 CentOS7,确保你的系统是全新的,否则会有不清楚的包依赖或冲突问题

  • 更新内核

    yum update -y
    
  • 安装基础开发组相关包

    yum groupinstall "Development Tools"
    
  • 安装依赖的软件包

    yum install -y automake autoconf pkgconfig libtool gtk2-devel openssl-devel glibc-devel gmp-devel cmake psmisc
    
  • 先上传 tc.tgz ,然后解压,进入 tc 目录中

    [root@localhost ~]# ls
    anaconda-ks.cfg  tc.tgz
    [root@localhost ~]# tar -xzf tc.tgz 
    [root@localhost ~]# ls
    anaconda-ks.cfg  tc  tc.tgz
    [root@localhost ~]# cd tc
    [root@localhost tc]# ls
    tpm-emulator  trousers-0.3.15  trusted-computing-projectv0.3
    

编译 tpm-emulator

  • tpm-emulator 的目录结构如下:

    [root@localhost tc]# cd tpm-emulator/
    [root@localhost tpm-emulator]# ls
    AUTHORS  build.bat  build.sh  ChangeLog  CMakeLists.txt  config.h.in  crypto  mtm  README  tddl  tpm  tpmd  tpmd_dev
    
  • 新建 build 并进入目录中,然后 CMake 生成 Makefile

    [root@localhost tpm-emulator]# cd build
    [root@localhost build]# ls
    [root@localhost build]# cmake ..
    -- The C compiler identification is GNU 4.8.5
    -- Check for working C compiler: /usr/bin/cc
    -- Check for working C compiler: /usr/bin/cc -- works
    -- Detecting C compiler ABI info
    -- Detecting C compiler ABI info - done
    -- Configuring done
    -- Generating done
    -- Build files have been written to: /root/tc/tpm-emulator/build
    
  • 编译安装 tpm-emulator

    [root@localhost build]# make -j
    此处省略输出。。。
    
    [root@localhost build]# make install
    [ 58%] Built target tpm
    [ 80%] Built target mtm

    -- Removed runtime path from "/usr/local/bin/tpmd"
    
    [root@localhost build]# modprobe tpmd_dev
    
  • 启动 tpm-emulator

    [root@localhost build]# tpmd -f
    tpmd.c:390: Info: starting TPM Emulator daemon (1.2.0.7-475)
    tpmd.c:93: Info: parsing options

    tpm_testing.c:261: Info: Self-Test succeeded
    tpm_startup.c:43: Info: TPM_Startup(1)
    

编译 trousers

  • 新建一个终端,进入 trousers 目录,通过 bootstrap 生成 configure

    [root@localhost trousers-0.3.15]# sh bootstrap.sh 
    + aclocal
    + libtoolize --force -c
    libtoolize: putting auxiliary files in `.'.
    libtoolize: copying file `./ltmain.sh'
    libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and
    libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
    libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
    + automake --add-missing -c --foreign
    + autoconf
    
  • 通过 configure 生成 Makefile

    [root@localhost trousers-0.3.15]# ./configure
    此处省略输出。。。
    
  • 编译安装 trousers

    [root@localhost trousers-0.3.15]# make -j
    此处省略输出。。。
    
    [root@localhost trousers-0.3.15]# make install
    此处省略输出。。。
    
  • 确认是否安装成功,检查是否存在:/usr/local/var/lib/tpm/ 目录

    [root@localhost trousers-0.3.15]# ls /usr/local/var/lib/tpm/
    
  • 启动 trousers

    [root@localhost trousers-0.3.15]# tcsd -e -f
    TCSD TDDL ioctl: (25) Inappropriate ioctl for device
    TCSD TDDL Falling back to Read/Write device support.
    TCSD trousers 0.3.15: TCSD up and running.
    

    同时,上一个终端中 tpm-emulator 应有输出,如下所示:

    tpm_startup.c:43: Info: TPM_Startup(1)
    tpm_capability.c:697: Info: TPM_GetCapability()
    tpm_cmd_handler.c:4084: Info: TPM command succeeded
    tpm_capability.c:697: Info: TPM_GetCapability()
    tpm_cmd_handler.c:4084: Info: TPM command succeeded

    tpm_capability.c:697: Info: TPM_GetCapability()
    tpm_cmd_handler.c:4084: Info: TPM command succeeded
    

验证安装环境

  • 新开一个终端,进入 trusted-computing-projectv0.3 目录中,make clean 清除之前的构建,然后编译。有警告是正常的,不是错误就行。

    [root@localhost trusted-computing-projectv0.3]# make clean
    此处省略输出。。。
    
    [root@localhost trusted-computing-projectv0.3]# make
    此处省略输出。。。
    
  • 到 init 中,take ownship 和创建 mig_key

    [root@localhost trusted-computing-projectv0.3]# cd init/
    [root@localhost init]# ls
    create_mig_key  create_mig_key.c  Makefile  Tspi_TPM_TakeOwnership01  Tspi_TPM_TakeOwnership01.c
    [root@localhost init]# ./Tspi_TPM_TakeOwnership01 -v 1.2
    
    <<<test_start>>>
    Testing Tspi_TPM_TakeOwnership01
    TESTSUITE_OWNER_SECRET:(null)
    TESTSUITE_SRK_SECRET:(null)
            1 PASS  :  Tspi_TPM_TakeOwnership01  returned (0) TSS_SUCCESS
    Cleaning up Tspi_TPM_TakeOwnership01
    <<<end_test>>>
    [root@localhost init]# ./create_mig_key -v 1.2
    Please input Migratable key's migration secret
    Enter PIN:
    Verifying - Verify PIN:
    success
    
  • 到 SealUnseal 目录中,测试 seal 和 unseal,能 unseal 出来能通过说明环境没问题

    [root@localhost init]# cd ../SealUnseal/
    [root@localhost SealUnseal]# ls
    extend  extend.c  hex-out.h  Makefile  seal  seal.c  sealedData  seal_file  seal_file.c  test  test.c  unseal  unseal.c
    [root@localhost SealUnseal]# ./seal -v 1.2

其他

关于 tpmd 和 tcsd 出现的一堆问题,一般是 tpmd 没有清理干净,这样做一般能解决:

[root@localhost build]# tpmd deactivated
[root@localhost build]# killall tpmd
[root@localhost build]# tpmd clear
[root@localhost build]# tpmd deactivated
