SECURE eSIM SUBSCRIPTION TRANSFER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18317323 titled 'SECURE eSIM SUBSCRIPTION TRANSFER

Simplified Explanation

The described embodiments of this patent application propose techniques for securely transferring a cellular wireless service subscription from one device to another. This is done through communication with servers of a mobile network operator (MNO) and involves encrypting an activation code used for the transfer.

  • The MNO provisioning server encrypts the activation code using a session key generated from a one-time-use eUICC public key and a one-time-use server private key.
  • The encrypted activation code is protected from malicious third parties as only the eUICC of the source device can decrypt it by generating an identical session key.
  • The eUICC of the source device deletes the eSIM profile before providing the activation code to the target device, preventing eSIM profile cloning.

Potential Applications

  • Secure transfer of cellular wireless service subscriptions between devices.
  • Protection against unauthorized access and cloning of eSIM profiles.

Problems Solved

  • Ensures the secure transfer of cellular wireless service subscriptions without the risk of interception or cloning.
  • Prevents unauthorized access to eSIM profiles and protects user data.

Benefits

  • Enhanced security for transferring cellular wireless service subscriptions.
  • Protection against eSIM profile cloning and unauthorized access to user data.
  • Simplified and efficient process for transferring subscriptions between devices.


Original Abstract Submitted

The described embodiments set forth techniques for securely transferring a cellular wireless service subscription associated with an electronic subscriber identity module (eSIM) profile from a source wireless device to a target wireless device via communication with servers of a mobile network operator (MNO). An MNO provisioning server encrypts an activation code, used for transfer of the cellular wireless service subscription, with a session key generated based on a one-time-use eUICC public key and a one-time-use server private key. The encrypted activation code is protected from malicious third parties, as only the eUICC of the source wireless device can perform the decryption required by generating an identical session key to recover the activation code. The eUICC of the source wireless device deletes the eSIM profile from the eUICC before providing the activation code to the target wireless device to protect against eSIM profile cloning.
