Abstract

The invention is applicable to the technical field of Java card chips, and provides Java card chip communication equipment and a communication method; the Java card chip communication equipment comprises a Java card chip and a main security chip, and the Java card chip is connected with the main security chip; the Java card chip is used for installing a virtual machine, installing a first application and receiving and responding to a processing instruction of the first application; and the main security chip is used for installing a second application and receiving and responding to a processing instruction of the second application. By means of the method, occupation of the storage space of the Java card chip can be avoided, and separate management of authorities of different applicationscan be achieved.

Description

Technical field [0001] This application belongs to the field of Java card chip technology, and in particular relates to a Java card chip communication device, a communication method, and a computer-readable storage medium. Background technique [0002] The Java card chip usually has a virtual machine provided by the card vendor, and the user can use the storage space of the Java card chip, such as installing an application on the Java card chip by himself, and the user has the control authority to manage the Java card chip. [0003] However, when the card vendor needs to build the default application of the card vendor on the Java card chip, the authority management of the built-in default application of the card vendor is also the user instead of the card vendor, and if the card vendor’s built-in default application on the Java card chip will occupy User storage space. [0004] Therefore, it is necessary to provide a new method to solve the above technical problems. Summary of the...
