A method and apparatus for group session key and establishment using a certified migration key are described. In one embodiment, the method includes exporting of a protected certified migration key (CMK) to a target platform. In one embodiment, exporting of the protected CMK requires that the target platform is authorized for participation in a group and has a storage key, including attributes that comply with the group security policy. Once the protected CMK is exported, in one embodiment, a group master key is encrypted with a public portion of the CMK to form a protected group master key. Subsequently, the protected group master key is transmitted to the target platform. In one embodiment, possession of the group master key enables the target platform to participate in a secure group communication session. Other embodiments are described and claimed.
