Aiming at the limitation of single-domain authentication provided by Direct Anonymous Attestation(DAA),a dynamic trust-based cross-domain authentication mechanism of DAA is proposed,which quantizes trust relation to trust value between 0 and 1,realizes cross-domain authentication by comparing trust value with expectation value. Experimental result proves the mechanism can effectively diminish the workload of Trusted Platform Module(TPM) and reduce the time expense on DAA authentication,and the variety of trust value is given.
