METHOD FOR PERSONALIZING A SAFETY ELEMENT OF A MOBILE TERMINAL DEVICE

摘要

The invention relates to a method for personalizing a security element (SE) of a mobile end device (EG), in particular in the form of a smart card chip of a communication end device. The invention comprises the pre-personalizing of the security element (SE) within the framework of its production process and the final personalizing of the security element (SE) upon the first-time use of the end device (EG) by a user (N), wherein a communication link is established between the end device (EG) and a trust center (TC) of a communication network operator. Within the framework of the pre-personalization of the security element (SE), a master key (MK) unique to the security element (SE) is ascertained and transmitted to the trust center (TC). Within the frame-work of the final personalization of the security element (SE), personal data of the user are transmitted upon the first-time use of the end device (EG) to the trust center (TC) and linked there with the master key (MK) to form a modified master key (MK). The security element (SE) is personalized with the modified master key (MK).
