Abstract
Embodiments utilizing secret keys for authentication and/or encrypted communication are described. In certain embodiments, authentication data is provided from a source network communication device to a target network communication device that allows a computing server to verify that the key migration is authorized by the source network communication device. The authentication data also enables the data provider and the target network communication device to independently determine a temporary key for establishing a secure communication channel between the service provider and the target network communication device and/or determine a new key for the target network communication device. In some implementations, the authentication data may be exchanged between the source and target network communication devices between offline without involvement of the computing server. When the target network communication device later connects to the computing server, the authentication data may be used to verify that the key migration is authorized and/or generate key(s).
