Abstract
An electronic device (such as a cellular telephone) automatically installs and optionally personalizes a purposed application (which is sometimes referred to as an ‘applet’) on a secure element in the electronic device (which is sometimes referred to as ‘applet creation’). In particular, when a digitally signed installation package containing the applet is received from an installing device (such as a server), the secure element verifies the digital signature of the installation package using an encryption key associated with a vendor of the secure element. Then, the secure element installs the applet. In addition, the secure element may optionally export user data from another applet installed on the secure element. Moreover, the secure element may personalize the installed applet using the user data from the other applet. In this way, the electronic device provides a scalable installation solution while allowing personalization from the other applet.
