Abstract
A method for preparing an eSIM for provisioning is provided. The method can include a provisioning server encrypting the eSIM with a symmetric key. The method can further include the provisioning server, after determining a target eUICC to which the eSIM is to be provisioned, encrypting the symmetric key with a key encryption key derived based at least in part on a private key associated with the provisioning server and a public key associated with the target eUICC. The method can additionally include the provisioning server formatting an eSIM package including the encrypted eSIM, the encrypted symmetric key, and a public key corresponding to the private key associated with the provisioning server. The method can also include the provisioning server sending the eSIM package to the target eUICC.
