Embodiment Construction

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023] The present invention generally involves downloading an application to a portable device, usually a mobile phone. A user may wish to download new features or applications such as tools and games and general content items to upgrade the phone. Applications may be provided by third-party developers independent of the original phone manufacturer. For authorization and security reasons, the user, and often the phone manufacturer, wants to control the phone from being rendered inoperable or corrupted by new applications. As mentioned above, a system has been invented in which the authenticity of the application can be checked by means of a digital signature attached to the application, and attribute certificates can likewise be downloaded in order to control the application only through the interface in the device (usually Called an API (Application Programming Interface), it provides limited access to existing hard...

Abstract

The invention relates to a method for loading an application (2) into a device (1), and generally to downloading of applications into portable devices, typically mobile telephones. The method includes the steps of: downloading the application (2) with a signature to the device; coupling the signature of the application to a predefined attribute certificate stored in the device; and installing the application together with said attribute certificate . Preferably, the signature of the application is coupled to a root certificate which in turn is linking the application to a predefined attribute certificate. The invention also relates to such a device (1) and a smart card (6) usable in such a device.

Description

technical field [0001] The invention relates to a method for loading an application program into a device, and more particularly relates to the control of the interface between the application program and the device. The invention also relates to such a device and to a smart card usable in such a device. Background technique [0002] WO 00 / 59225 and US-B1-6,223,291 disclose secure wireless e-commerce systems together with the field of wireless networks. The system includes a wireless network operator authentication authority having a root public key certificate and at least one attribute authority having a digital certificate dependent on the root public key certificate. Property authorities can be accessed by wireless client devices over a wireless network. The digital certificate is passed to the wireless device by the property authority. Attribute authority is authenticated to the wireless client device using a digital certificate and a root public key certificate prel...
