Abstract: A method for managing a secure element which is embedded into a host unit. The described method comprises (a) transmitting a request for a management script from the host unit to a program element of the secure element, (b) at the program element, generating a management script in accordance with the request and encrypting the generated management script, (c) transmitting the encrypted management script from the program element to the host unit, (d) transmitting the encrypted management script from the host unit to a secure domain of the secure element, and (e) at the secure domain, decrypting and executing the management script.

Abstract: Aspects of various embodiments are directed to the communication of wireless data. In a particular embodiment, an apparatus includes a master/wireless communication circuit and a slave circuit that carries out a secure function. The master generates session initiation commands, and the slave is responsive to these commands by generating and storing a session ID. In response to the receipt and validation of user-input data, the slave accesses and locally stores the session ID. Upon the initiation of and/or during a wireless communication process, the slave again accesses the session ID and compares the accessed session ID with the locally stored session ID, and facilitates communication based on the comparison (e.g., communication is not permitted if the comparison does not indicate a match).

Abstract: A current operating system that is stored in a persistent storage circuit of a secure element is replaced by receiving a set of migration rules that specify changes to a set of data object types. Based upon the set of migration rules, a migration engine identifies data objects stored in a persistent storage circuit and corresponding to the set of data object types. For each of the identified data objects: a subset of the migration rules are selected that correspond to a data object type that corresponds to a particular data object, and based upon the selected subset, the particular data object is transformed. A new operating system can then be enabled.
