Abstract
An application is loaded into a device, such as downloading an application into a portable device, such as a mobile telephone, by downloading the application with a signature to the device. The signature of the application is coupled to a predefined attribute certificate stored in the device. The application and said attribute certificate are then installed together. The signature of the application may be coupled to a root certificate that in turn links the application to a predefined attribute certificate.
