Research on direct anonymous attestation mechanism in enterprise information management

Privacy leakage is becoming more and more serious in enterprise information management. To solve the poor security problems, by introducing short signatures into enterprise information managements, this paper proposes a novel direct anonymous attestation scheme. The novel scheme is based on a novel short signature scheme, which is applied into the member joining and signature phases. It simplifies the signing and verification process of member certificates and reduces its computing costs. Under the security hypothesis of Decision Diffie-Hellman and q-Strong Diffie-Hellman difficult problems, the novel attestation scheme meets the provable security of the trusted platform module specifications.
