Methods for anonymous authentication and key exchange are presented. In one embodiment, a method includes initiating a two-way mutual authentication between a device and a remote entity. The device remains anonymous to the remote entity after performing the authentication. The method also includes establishing a mutually shared session key for use in secure communication, wherein the initiating and the establishing are in conjunction with direct anonymous attestation (DAA).
