Data transfer and management between secure element servers
The patent US11997495B2 outlines a method for transferring and managing data packages between two portable secure element (SE) servers: one implemented in a portable device and the other in an embedded Universal Integrated Circuit Card (eUICC) within a user's device. The method emphasizes establishing offline communication using local data transport protocols, such as Bluetooth, Near Field Communication (NFC), or Wi-Fi Direct, without requiring an internet connection. The process includes secure transfer functionalities for data packages, which may consist of eUICC operating system upgrades and eSIM profiles. Additionally, the method ensures end-to-end security of the data packages, allowing them to either remain in the first portable SE server or be deleted after transfer.
The patent also describes the configuration of the portable device and the user's device, detailing the means for establishing secure offline communication and implementing the necessary transfer functionalities. Both devices can be smartphones, tablets, or wearables that support eUICC technology. A Local Profile Assistant (LPA) may be included in either device to facilitate the transfer of data packages. The claims further specify that the transfer functionalities can be executed using native code or any programming language supported by the portable SE servers, and the patent encompasses non-transitory digital data storage mediums that encode machine-executable instructions for carrying out the described methods.
