Abstract
A method and apparatus for direct anonymous attestation from bilinear maps. In one embodiment, the method includes the creation of a public/private key pair for a trusted membership group defined by an issuer; and assigning a unique secret signature key to at least one member device of the trusted membership group defined by the issuer. In one embodiment, using the assigned signature key, a member may assign a message received as an authentication request to prove membership within a trusted membership group. In one embodiment, a group digital signature of the member is verified using a public key of the trusted membership group. Accordingly, a verifier of the digital signature is able to authenticate that the member is an actual member of the trusted membership group without requiring of the disclosure of a unique identification information of the member or a private member key to maintain anonymity of trusted member devices. Other embodiments are described and claimed.
