Abstract
A method for personalizing embedded secure elements, eSE, allows for simplified manufacturing before being integrated into host devices. An eSE implements services executed by an embedded operating system, OS, whereupon it is loaded into the eSE. The non-personalized eSE comprises an OS loader and a master cryptographic key common to a plurality of secure elements. It can therefore be produced in large numbers. The OS loader obtains an operating system package from a server and installs it. In response to the installation, the OS loader generates a derivation cryptographic key by diversifying the master cryptographic key, and then the OS generates personalized data by deriving pre-personalization data with the derivation key. The eSE, deployed in the field in a simple non-personalized state, is fully personalized without exchanging secret personalized data.
