实验三 密码模块实现 6 基于商用密码标准的密码模块的实现 实现简单的密码引擎，能够提供对称密码算法、非对称密码算法、Hash算法等的密码服务。 综合性 1.理解密码系统固件、接口等的设计和开发流程； 2．参考《GMT 0018-2023密码设备应用接口规范》等商用密码标准设计实现密码算法进行加密/解密、签名/验签、密钥生成/导出等的接口； 3.与其他商用密码模块进行兼容性测试。

实验三 密码模块实现

1-3 学时实践要求（30 分）

  1. 阅读学习 《GM/T 0016智能密码钥匙密码应用接口规范》和《GMT 0018 密码设备应用接口规范》

《GM/T 0016智能密码钥匙密码应用接口规范》 ：这是智能密码钥匙设备的应用接口标准，规定了密码相关应用接口的函数、数据类型、参数的定义和设备的安全要求。
《GMT 0018密码设备应用接口规范》：这是服务端密码设备应用接口的算法标识、数据结构和接口函数的标准。

  1. 在 Ubuntu或openEuler中（推荐 openEuler）中编译运行附件中《GM/T 0016智能密码钥匙密码应用接口规范》相关代码，并新增完成标准中至少一项功能。使用Markdown记录详细记录实践过程，每完成一项功能或者一个函数git commit 一次。（15分）

  2. 在 Ubuntu或openEuler中（推荐 openEuler）中编译运行附件中《GMT 0018 密码设备应用接口规范》相关代码，并新增完成标准中至少一项功能。（15分）

  3. 实验记录中提交 gitee 课程项目链接，提交本次实验相关 git log运行结果。

valgrind ./signatureTest

程序在尝试执行 libgm3000.1.0.so 动态库中的 libusb_get_device_list

函数时发生了段错误。具体的错误信息如下：

Invalid read of size 4：

这表明程序试图读取一个无效的内存地址（0x30），这个地址既不是栈内存、也不是通过 malloc 分配的内存，也不是最近释放的内存。

Address 0x30 is not stack'd, malloc'd or (recently) free'd：

这进一步确认了上述错误，指出地址 0x30 不是栈内存、动态分配的内存或最近释放的内存。 Process terminating with

default action of signal 11 (SIGSEGV)：

程序因为接收到信号 11（段错误）而终止。

这个段错误可能是由于动态库 libgm3000.1.0.so 中的内存访问错误引起的。据推测，可能需要检查库文件的完整性和兼容性，以及代码中的指针和内存操作。使用 GDB 和 Valgrind 进一步调试或许可以帮助找到具体的问题所在。
