Single-point security certification method for having access to enterprise data through mobile application

The invention discloses a single-point security certification method for having access to enterprise data through a mobile application. A single-point security certification gateway supports multiple mainstream safety certification protocols comprising Kerberos, NTLM, SAML and the like and provides a uniform programming interface for third-party certification modules. The single-point security certification gateway sets a user name, a code and an identity certificate for a mobile terminal application, and dynamic, transparent and safe certification between the mobile terminal application and the enterprise data service can be completed through the security certification protocol allocated according to demands. Meanwhile, the single-point security certification gateway and the enterprise data service can conduct safe interaction regularly, a secret key is updated, in this way, the safety feature that the certification key between the mobile terminal application and the enterprise data service is dynamically updated is well achieved, the security of enterprise data is guaranteed, and the risk of enterprise data leakage is lowered.
