我想使用Azure的IOT-SDK-CSHARP，以提供一个基于Linux的设备上蔚蓝的IOT使用TPM作为认证机制的dps。
我添加了一个TPM模块到覆盆子板和配置内核/的DeviceTree。当检测到TPM芯片和在/ dev / tpm0设备在linux显示出来。 Addionaly我包括了所有的先决条件进入Linux映像在Linux上运行（https://github.com/dotnet/core/blob/master/samples/YoctoInstructions.md）一个自包含.NET的核心应用。它可以运行.NET的核心应用程序...我测试用c＃设备SDK简单的IOT毂连接。
接下来，我试图从.NET核心访问TPM模块。因此，我写了这个程序，使用SecurityProviderTpmHsm从Microsoft.Azure.Devices.Provisioning.Security读取TPM endorsementKey。
using System;
using System.Text;
using Microsoft.Azure.Devices.Provisioning.Security;
using Microsoft.Azure.Devices.Shared;
namespace TPMTest
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
var tpmProvider = new SecurityProviderTpmHsm("test");
var test = tpmProvider.GetEndorsementKey();
Console.WriteLine(BitConverter.ToString(test));
}
}
}
这工作在Windows机器上，而是用一个自包含包（DOTNET发布的linux -r臂）失败了Linux臂机上。
Hello World!

我读了一些问题，在GitHub上缺少bcrypted.dll。据我了解，一些加密功能都没有在Linux版本的.NET核心2.x的移植。 https://github.com/dotnet/corefx/issues/7023所以，我尝试了.NET的核心3.x的预览，它支持AES-GCM等......但我遇到了同样的错误。
不知道，如果这个问题与我的问题。
是否有丢失的依赖，这是我需要在我的Linux映像？难道是一般支持，能够使用在.NET的核心TPM模块基于Linux的机器？
Microsoft.Azure.Devices.Provisioning.Security.Tpm是依靠Microsoft.TSS 2.0.1 NuGet包具有仅适用于Linux-x64的二进制文件。
为了使其工作：
<PropertyGroup Condition=" '$(RuntimeIdentifier)' == 'linux-x64' Or '$(OS)' == 'Unix' Or '$(OS)' == 'Linux'">
这
<PropertyGroup Condition=" '$(RuntimeIdentifier)' == 'linux-x64' Or '$(RuntimeIdentifier)' == 'linux-arm' Or '$(OS)' == 'Unix' Or '$(OS)' == 'Linux'">
