An apparatus and method is provided for a direct anonymous attestation scheme from short-group signatures. The method may include the creation of a group public/private key pair for a trusted membership group defined by an issuer; and assigning a cryptographic pair that is combined with a unique private member value to form a private membership key. A trusted member device generates the unique private member value during a join procedure of a trusted membership group. In one embodiment, the private member value of the private membership key is unknown to the issuer. A member may sign a message with the private membership key to form a short-group digital signature that is verified using a public key of the trusted membership group to maintain anonymity of trusted member devices. A size of the private membership key may be reduced to enable storage within a trusted platform module. Other embodiments are described and claimed.
