1. Field of the Invention

2. Description of the Related Art
With active development of applications for mobile terminals, application servers provide users with various application packages in downloadable form.
To install an application onto a mobile terminal using an application package, the mobile terminal has to receive signature information signed with a signature key suitable for the mobile terminal together with the application package.
Currently, an application package is associated with a single piece of signature information.
To provide an application to a particular mobile terminal, multiple application packages are created corresponding in number to terminal types and each such application package is associated with signature information specific to a particular terminal type.
Creating multiple application packages for different terminal types is an unnecessary use of time and effort. In addition, whenever a new type of mobile terminal is manufactured, new application packages need to be created and maintained.
