#SAML Channel Binding Extensions v1.0 Committee Specification 01 published

OASIS Members,

We are pleased to announce the approval and publication of a new Committee Specification by the members of the OASIS Security Services (SAML) TC:

SAML V2.0 Channel Binding Extensions Version 1.0
Committee Specification 01
10 July 2013


Protocol extensions enable extension-aware SAML requesters and responders to modify protocol behavior in a generic, layered fashion. This specification defines an extension to the SAML V2.0 protocol specification that supports the use of channel bindings in conjunction with SAML profiles. It also includes a new SAML profile that applies the extension to a set of profiles that fit a particular communication pattern.

The prose specification and related files are available here:
