Embodiment Construction

[0022] Detailed description of preferred embodiments

[0023] The present invention generally involves downloading an application to a portable device, usually a mobile phone. The user may wish to download new features or applications, such as tools and games and general content items to upgrade the phone. The application can be provided by a third-party developer independent of the original phone manufacturer. For authorization and security reasons, users, and usually phone manufacturers, want to control the phone from being rendered inoperable or damaged by new applications. As mentioned above, a system has been invented in which the reliability of the application can be checked by a digital signature attached to the application, and the attribute certificate can also be downloaded to control the application to only allow it to pass through the interface in the device (usually Called API (application programming interface)), which provides limited access to existing hardware ...

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 specifically to the control of the interface between the application program and the device. The invention also relates to such a device and a smart card that can be used in such a device. Background technique [0002] WO 00 / 59225 and US-B1-6,223,291 disclose a secure wireless e-commerce system together with the wireless network field. The system includes a wireless network operator certification authority with a root public key certificate and at least one attribute authority with a digital certificate dependent on the root public key certificate. The attribute authority can be accessed by wireless client devices through a wireless network. The digital certificate is passed to the wireless device by the attribute authority. The digital certificate and the root public key certificate preloaded into the wireless client device under the authorization of the wireles...
