WCF TCP 传输安全和 WIF

Question

我的公司使用 WIF（Windows Identity Foundation）来保护我们的服务。目前我们仅通过 HTTPS 使用 WIF。然而，我们需要保护 TCP 端点，但我遇到了一些麻烦。

我遇到以下异常：

The '{binding name}'.'http://tempuri.org/' binding for the '{IService}'.
'http://tempuri.org/' contract is configured with an authentication mode that requires 
transport level integrity and confidentiality. However the transport cannot provide 
integrity and confidentiality.

为了将 WIF 纳入图片中，我们必须在服务主机内执行此操作：

var istp = new IssuedSecurityTokenParameters(_TokenType, _IssuerAddress, _IssuerBinding) // issuer address/binding do not matter for this, but must provide something
{
    RequireDerivedKeys = false, 
    KeyType = System.IdentityModel.Tokens.SecurityKeyType.BearerKey
}; 

TransportSecurity = new TransportSecurityBindingElement();
TransportSecurity.EndpointSupportingTokenParameters.Signed.Add(istp);
TransportSecurity.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12; 

我无法取出这些代码行，但我不知道我缺少什么配置来实现此目的与 TCP 一起工作。任何帮助都会很棒。
