public class ChannelBinding extends java.lang.Object
The JGSS accommodates the concept of caller-provided channel binding information. Channel bindings are used to strengthen the quality with which peer entity authentication is provided during context establishment. They enable the JGSS callers to bind the establishment of the a security context to relevant characteristics like addresses or to application specific data.The caller initiating the security context must determine the appropriate channel binding values to set in the GSSContext object. The acceptor must provide identical binding in order to validate that received tokens possess correct channel-related characteristics.
Use of channel bindings is optional in JGSS. Since channel- binding information may be transmitted in context establishment tokens, applications should therefore not use confidential data as channel-binding components.
