使用 X509Certificates 保护 WCF 服务

Question

我正在处理的场景涉及一个 ASP.NET Web 应用程序与一个使用 netTcpBinding 的自托管 WCF 服务进行通信。这两个组件托管在不同的机器上。 Web服务器是DMZ中的单机，与应用服务器没有信任关系。

我希望在传输级别保护通信。据我了解，如果客户端和应用服务器都安装了合适的X509证书，它们可以相互认证，数据交换也可以加密。

我已经为 Web 服务器提供了 ClientAuthentication 证书，并为应用程序服务器提供了 ServerAuthentication 证书。在每种情况下，证书都存储在 LocalMachine\My 存储中。我已确保私钥可用于所有证书，并且应用程序池身份和 BUILTIN\LOCAL 身份（分别在 Web 和应用程序服务器上）具有对私钥的完全访问权限。我还将证书的 public 关键部分（即 .cer 文件）复制到对面服务器上的 LocalMachine\TrustedPeople 存储区。

配置如下所示：

应用服务器

<services>
  <service behaviorConfiguration="DefaultServiceBehavior" name="Evs.Application.Services.XXXXXProvider">
    <endpoint address="net.tcp://localhost:8000/Evs.Application.Services/XXXXXServiceCert"
              binding="netTcpBinding" bindingConfiguration="SecureCertificateNetTcpBinding" contract="Evs.Application.Contracts.IXXXXXProvider"
              behaviorConfiguration="endpointBehavior"/>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="DefaultServiceBehavior">
      <serviceDebug includeExceptionDetailInFaults="true" />
      <serviceCredentials>
        <serviceCertificate storeLocation="LocalMachine" storeName="My" x509FindType="FindByThumbprint" findValue="xxxxxxxxxxxxxx"/>
      </serviceCredentials>
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
    <binding name="SecureNetTcpBinding">
      <security mode="Transport" />
    </binding>
    <binding name="SecureCertificateNetTcpBinding">
      <security mode="Transport">
        <transport clientCredentialType="Certificate" />
      </security>
    </binding>
  </netTcpBinding>
</bindings>

网络服务器

<client>
  <endpoint address="net.tcp://app-ext-01.prod.mydomain.com:8000/Evs.Application.Services/XXXXXServiceCert"
            behaviorConfiguration="secureEndPointBehaviour" binding="netTcpBinding"
            bindingConfiguration="SecureCertificateNetTcpBinding" contract="Evs.Application.Contracts.IXXXXXProvider"
            name="XXXXXProvider"/>
<client>
<behaviors>
  <endpointBehaviors>
    <behavior name="secureEndPointBehaviour">
      <clientCredentials>
        <clientCertificate findValue= "xxxxxxxxxxxxxxxxxxx"
         storeLocation="LocalMachine" storeName="My"
         x509FindType="FindByThumbprint"/>
      </clientCredentials>
    </behavior>
  </endpointBehaviors>
</behaviors>
<bindings>
  <netTcpBinding>
    <binding name="SecureCertificateNetTcpBinding">
      <security mode="Transport">
        <transport clientCredentialType="Certificate" />
      </security>
    </binding>
  </netTcpBinding>
</bindings>

在我用于测试它的暂存环境中，对服务的调用失败，出现以下异常（从服务器端日志中检索）

System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.9840000'. ---&amp;gt; System.IO.IOException: The read operation failed, see inner exception. ---&amp;gt;

任何人都可以建议我需要对这个配置做些什么才能让它工作吗？

我相信你错过了：

服务器端

<serviceCredentials>
  <clientCertificate>
    <authentication certificateValidationMode="PeerTrust" />
  </clientCertificate>
</serviceCredentials>

客户端

<clientCredentials>
  <serviceCertificate>
    <authentication certificateValidationMode="PeerTrust" />
  </serviceCertificate>
</clientCredentials>
