    Abstract: An electronic device (such as a cellular telephone) automatically installs and personalizes updates to an applet on a secure element in the electronic device. In particular, when a digitally signed update package containing the update is received from an updating device (such as a server), the secure element identifies any previous versions of the applet installed on the secure element. If there are any previously installed versions, the secure element verifies the digital signature of the update package using an encryption key associated with a vendor of the secure element. Then, the secure element uninstalls the previous versions of the applet and exports the associated user data. Next, the secure element installs the update to the applet, and personalizes the new version of the applet using the user data.

    Abstract translation: 电子设备(例如蜂窝电话)在电子设备中的安全元件上自动安装并个性化对小应用程序的更新。 特别地,当从更新设备(例如服务器)接收到包含更新的数字签名的更新包时,安全元件识别安装在安全元件上的小应用程序的任何先前版本。 如果有任何先前安装的版本,则安全元件使用与安全元件的供应商相关联的加密密钥验证更新包的数字签名。 然后,安全元素会卸载以前版本的applet并导出关联的用户数据。 接下来,安全元件将更新安装到小程序,并使用用户数据个性化新版本的小应用程序。
