Transfer of an eSIM from a source device to a target device includes re-encryption of sensitive eSIM data, e.g., eSIM encryption keys, financial transaction credentials, transit authority credentials, and the like, using new encryption keys that include ephemeral elements applicable to a single, particular transfer session between the source device and the target device. The sensitive eSIM data encrypted with a symmetric key (Ks) is re-wrapped with a new header that includes a version of Ks encrypted with a new key encryption key (KEK) and information to derive KEK by the target device. The re-encrypted sensitive SIM data is formatted with additional eSIM data into a new bound profile package (BPP) to transfer the eSIM from the source device to the target device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic subscriber identity module transfer credential wrapping","description":"Embodiments described herein relate to credential wrapping for secure transfer of electronic SIMs (eSIMs) between wireless devices.
