    Abstract: A method for personalizing a software, in particular an operating system OS, in a secure element, SE, includes the steps of loading a software image into the memory of the SE; loading a software personalization record comprising personalization data into the memory of the SE; and personalizing the loaded software image using the software personalization data. Personalization of the software image is initiated by an internal agent of the SE. Initiation personalization of the software image by the internal agent is triggered by a trigger event that is detected by the internal agent, the trigger event being unrelated to software personalization.

    Abstract: A method and an apparatus for updating software loaded on a secure element, SE, which SE comprises an update agent handler, and an update agent. In a first step, a request to backup a current version of software loaded on the SE is received at the SE. The request is sent from a device, external to the SE. Upon receiving the backup request, the SE performs a secure backup of the current software version, and returns the software backup to the device, to be stored thereon. In a further step, the SE performs an update process of the current software version, to obtain an updated software version. If the update process fails, a rollback is performed at the SE to restore the software backup as a new current soft-ware version on the SE.

    Abstract: A method, a data structure, and an update agent for implementing a scheme for downloading an operating system image onto a secure element. The update agent receives from an external device an installation package for installing an operating system onto the secure element. The update agent requests control of the secure element and loads the operating system received with the installation package into the secure element, after which control of the secure element is transferred to the operating system.
