Abstract
A method and apparatus for establishing a secure session with a device without exposing privacy-sensitive information are described. In one embodiment, the method includes the authentication of a digitally signed message received from a hardware device. In one embodiment, a digital signature, created by a private signature key of the hardware device, is authenticated according to a public key of an issuer without disclosure of an identity of the hardware device. The digital signature is a signature of an ephemeral DH public key, which the verifier is now assured comes from a trusted device. An encrypted and authenticated session ('secure session') is established with the authenticated hardware device according to a key exchange using this signed ephemeral DH public key. Other embodiments are described and claimed.
