Claim 7:
8. The method of claim 6, wherein Step 101 is specifically that the command of the upper host received by the fingerprint management chip is an assertion-obtaining command;
after in Step 103 the security environment chip determines the value of the fingerprint authentication identifier in the option parameter is the second preset value, the method further comprises: determining, by the security environment chip, a value of a key authentication identifier in the option parameter, and based on the determining the value of the key authentication identifier is the first preset value, executing Step 105; based on the determining the value of the key authentication identifier is the second preset value, executing Step 107; and
when in Step 103 the security environment chip determines that the value of the fingerprint authentication identifier in the option parameter is the second preset value and the security environment chip determines that the value of the key authentication identifier in the option parameter is the second preset value, Step 107 is specifically: setting, by the security environment chip, the authentication mode confirmation identifier according to the value of the fingerprint authentication identifier and the value of the key authentication identifier, obtaining, by the security environment chip, the client data from the assertion-obtaining command, generating the data to be signed according to the authentication mode confirmation identifier and the client data, performing the signature operation on the data to be signed and generating the signature result.
