presetting a corresponding certificate field mapping table for a driving library corresponding to each certificate reading hardware module, wherein the certificate field mapping table is used for realizing keyword mapping of field information of each type of certificate;
and configuring a certificate information output mapping table for application requirements of all application programs, wherein the certificate information output mapping table comprises a mapping of the application requirements of each application program and data source information, the data source information represents a data source of requirement certificate information of the application requirements of each application program, and the data source represents a position of the requirement certificate information in a certificate.
6. The SP service implementation for multiple credentials of claim 5 wherein the credential read instructions comprise a credential data source of an application requirement,
the method for matching the corresponding target certificate reading hardware module based on the preset certificate reading capability matching mechanism according to the certificate reading instruction, calling the target certificate reading hardware module to read the certificate information comprises the following steps:
analyzing the certificate reading instruction to obtain a certificate data source of application requirements;
determining target application requirements according to the certificate data source;
judging whether target data source information corresponding to the target application requirement exists in the certificate information output mapping table, and if not, feeding back certificate reading failure information to the application program; if so, determining a target certificate and a target data source according to the target data source information;
judging whether a target driving library corresponding to the target certificate exists in the certificate field mapping table, and if not, feeding back certificate reading failure information to the application program; if yes, determining target module reading capability information corresponding to the corresponding target certificate reading hardware module according to the target driving library;
determining field keywords of the target certificate which can be read by the target certificate reading hardware module according to the target module reading capability information;
obtaining a demand keyword string of demand certificate information of the target application demand according to the target data source;
judging whether the field keywords cover all the requirement keywords in the requirement keyword character string, and if not, feeding back evidence reading failure information to the application program; and if so, calling the target drive library to read the certificate information through the target certificate reading hardware module.
