Abstract: A method for transmitting a verification request to an identification module contained in a communication terminal device, comprising the following steps: (i) a request that was sent by an application of the communication terminal device instructing that the verification request should be transmitted to the identification module is received in a transmission means that is arranged physically separate from the communication terminal device, (ii) the verification request is transmitted by the transmission means to the identification module of the communication terminal device, (iii) a verification response to the verification request ascertained in the identification module is received in the transmission means, and (iv) a notification about the received verification response is transmitted by the transmission means to the application of the communication terminal devices.

Abstract: The subject innovation relates to a method with which a response to a request—said response having been ascertained by means of a communication terminal device can be securely transmitted to a data means, whereby the communication terminal device makes a selection from a plurality of response options. A specific key is associated with each of the response options, and the keys, which are in encrypted form, are received, together with the request, in the communication terminal device and they are decrypted in a means of the communication terminal device. On the basis of the selection made, the means ascertains the key that is associated with the selected response option, and the ascertained key is sent in a response message to the data means. The subject innovation also relates to a communication terminal device that is suitable for carrying out the method.

Abstract: The technique described herein relates to a method for transmitting data to an identification module in a mobile terminal device that can be connected to a mobile telecommunications network, making use of an OTA server that has a database with security information for a plurality of identification modules and that also has a first interface for transmitting secured information, especially OTA messages, to the identification modules. The data is secured in the OTA server by security information stored in the database, and the secured data is transferred via a second interface of the OTA server to a data center that is connected to the OTA server. The data is transmitted to the identification module by the data center. Moreover, the technique described herein also relates to a system for carrying out the method.
