摘要：
A method provides end-to-end security for transport of a profile to a target device (e.g., a mobile computing device) over at least one communications network that includes a plurality of nodes. In accordance with the method, the profile is encrypted for transport between the target device and an initial node of the network through which the profile is transported. The encryption is an end-to-end inner layer encryption performed prior to hop-to-hop encryption. The encrypting uses a public key of a public, private key pair. The private key is derivable from a seed securely provisioned in the target device using a public key algorithm. The encrypted profile is transmitted over the communications network to the target device.
