<span>该类封装了主叫方提供的通道绑定信息的概念。</span>
|
||
<span>信道绑定用于加强在上下文建立期间提供对等实体认证的质量。</span>
|
||
<span>它们使GSS-API调用者将安全上下文的建立与地址或应用程序特定数据等相关特性绑定。</span>
|
||
<p> <span>发起安全上下文的调用者必须确定要在GSSContext对象中设置的适当通道绑定值。</span> <span>接受者必须提供相同的绑定，以验证所接收的令牌具有正确的渠道相关特征。</span> </p>
|
||
<p> <span>通道绑定的使用在GSS-API中是可选的。</span> <span>ChannelBinding可以为被设置<a href="../../../org/ietf/jgss/GSSContext.html" title="org.ietf.jgss中的接口"><code>GSSContext</code></a>使用<a href="../../../org/ietf/jgss/GSSContext.html#setChannelBinding-org.ietf.jgss.ChannelBinding-"><code>setChannelBinding</code></a>第一呼叫之前方法<a href="../../../org/ietf/jgss/GSSContext.html#initSecContext-byte:A-int-int-"><code>initSecContext</code></a>或<a href="../../../org/ietf/jgss/GSSContext.html#acceptSecContext-byte:A-int-int-"><code>acceptSecContext</code></a>已经执行。</span> <span>除非已使用<code>setChannelBinding</code>方法设置GSSContext对象的<code>null</code>否则将假定<code>null</code> ChannelBinding。</span> </p>
|
||
<p> <span>从概念上讲，GSS-API将启动器和接收器地址信息以及应用程序提供的字节数组连接起来形成一个八位组字符串。</span> <span>该机构计算移到该八位组串的MIC和结合的MIC通过发射的上下文建立令牌<code>initSecContext</code>所述的方法<code>GSSContext</code>接口。</span> <span>相同的绑定由上下文接受者为其<code>GSSContext</code>对象设置，并且在处理<code>acceptSecContext</code>方法期间，以相同的方式计算MIC。</span> <span>计算出的MIC与在令牌中进行比较，如果中等收入国家不同，接受将抛出一个<code>GSSException</code>与主要代码设置为<a href="../../../org/ietf/jgss/GSSException.html#BAD_BINDINGS"><code>BAD_BINDINGS</code></a> ，以及上下文将不能成立。</span> <span>一些机制可以包括令牌中的实际信道绑定数据（而不仅仅是MIC）;</span> <span>因此，应用程序不应将机密数据用作通道绑定组件。</span> </p>
|
||
<p> <span>个别机制可能对通道绑定中可能出现的地址施加额外的限制。</span> <span>例如，机制可以验证信道绑定的发起者地址字段包含主机系统的正确网络地址。</span> <span>因此，便携式应用程序应确保它们为地址字段提供正确的信息，或省略寻址信息的设置。</span> </p>
