The Issue of Data Transfer for the Embedded SE on Mobile Devices

This paper describes the issue of data transfer for the embedded SE(Secure Element) on mobile devices. To enhance their security, current mobile devices provide the separate physical secure storage that contains the important and sensitive data for various security services. On the other hand, there is the problem of data migration for above secure storages such as the embedded SE. It is critical and essential problem in the embedded SEs because they cannot be removed from mobile devices. Thus, we explain the above problem in detail and would like to share the problem with service provider and mobile device manufacturers. To this end, we describe the security requirement for the secure data transfer of all data stored in embedded SEs. We also propose the secure data transfer schemes, which meet the proposed security requirements.
