Abstract

The present invention relates a method and a device for upgrading an Executable Load File, ELF, having dependencies, on a Secure Element, SE. The method comprises in a first step receiving a request for upgrading an ELF, the request comprising a first identifier, identifying a first ELF version loaded on the SE, a second identifier, identifying a second ELF version loaded on the SE, and an upgrade option. Upon receiving the request, dependencies of the first ELF version from other ELFs loaded or stored on the SE are determined. Subsequently, if dependencies have been determined, it is checked whether the upgrade request is allowed. If the update request is allowed, an upgrade session is started and the first ELF version is replaced with the second ELF version. The dependencies of the first ELF version are then linked to the second ELF version.
