In this step, the enterprise may bind the user certificate to the user system through an interface of the cloud connection center plug-in, so that an encrypted data tunnel is established between the user system and the cloud connection center. For example, as shown in FIG. 3, an interface for a user system to bind credentials is displayed.
Therefore, the data channel formed in this step is encrypted using a mixture of the certificate and Advanced Encryption Standard (AES).
The certificate-based hybrid cloud encrypted communication method further comprises the following steps: when a user side accesses the cloud server, the service bill is obtained through the cloud server plug-in, wherein the service bill is used for carrying out specified service. The plug-in is also used for maintaining the validity period of the service bills, and each service different bill has an expiration mechanism.

The cloud connection plug-in carries out additional signature on the file to be distributed by the user, a compressed package is exported and regenerated, and the compressed package can be introduced and used for other users again after passing the house in the cloud connection center.
The compressed packet is also used for data verification based on rules, namely the compressed packet has a data verification function at the same time so as to prevent tampering and unauthorized import. The user can check and import the service package. Of course, the user may also query the service by invoking cloud connection credit.
In this embodiment, in the certificate-based hybrid cloud encrypted communication method, a root certificate and a user certificate can be generated, and specific algorithm storage and distribution can be performed. Furthermore, there is a user certificate generation, distribution and binding mechanism. The cloud connection plug-in the embodiment is responsible for algorithm encapsulation and data encryption execution of a user local environment, and the algorithm can be compatible with tomcat, weblogic and was environments.
