Secure data package transfer between portable servers with end-to-end security
A recently granted patent (Publication Number: US11997495B2) outlines a method for transferring and managing data packages between portable secure element (SE) servers in devices like smartphones or tablets and embedded UICC (eUICC) servers local to the user's device. The method involves establishing offline communication using local data transport protocols like Bluetooth or NFC, enabling secure transfer of data packages between the SE servers. Additionally, end-to-end securing of data packages is implemented post-transfer, ensuring data integrity and status retention within the SE servers. The patent also covers the transfer of eUICC OS upgrades and eSIM profiles between the SE servers, enhancing the efficiency of data management processes.
Furthermore, the patent extends to the implementation of the method in portable devices like smart cards, secure memory cards, or smartphones supporting eUICC functionality. These devices are equipped with means for establishing secure offline communication, implementing transfer functionalities for data packages, and ensuring end-to-end security post-transfer. The inclusion of a Local Profile Assistant (LPA) in the devices enhances the transfer process, especially for downloading data packages in the second SE server. Overall, the patent focuses on optimizing data package transfer and management processes between portable SE servers and eUICC servers, catering to the evolving needs of secure data handling in modern devices.
