Abstract

It is possible to solve the problem that a server application owned by a secure device cannot be used by a client application owned by other secure device. A secure device includes: an application storage unit (202) for storing a client application as an application performing data processing; an address calculation unit (205) for judging whether the application storage unit (202) has a server application for passing data to/from the client; and a reference destination existence judging unit (210) for judging whether other secure device has a first server application when the address calculation unit (205) has judged that the application storage unit (202) does not have the first server application for passing data to/from the first client application.

Description

technical field [0001] The present invention relates to a security device and an external machine connected to the security device. Background technique [0002] Currently, attention is paid to IC cards as security devices. A multi-application compatible card that allows applications to be downloaded thereto after the card is issued has been developed for improving user convenience and lowering entry barriers for companies that want to provide IC card services. [0003] Recently, a device including a large-capacity memory in an IC chip that can be used as an extended memory protection area of ​​an IC card (hereinafter referred to as a secure memory card) has been proposed, and has made it possible to satisfy a large capacity of IC card application data. need. Because the secure memory card can be adapted to the size of the mobile machine, it is expected that the secure memory card will be inserted directly into a mobile machine with a slot for development to be used as an ...
