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

[ 80%] Built target mtm
[ 90%] Built target tpm_crypto

[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)

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
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
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>>>

<<<end_test>>>
[root@localhost init]# ./create_mig_key -v 1.2

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
