Abstract
The various examples are directed to establishing a secure session between a device and a server. The device and the server may establish a session key. The session key may be used for encrypting data. After authenticating the session key, the server may transmit secure session data to the device, and the device may store the secure session data. The server may transmit information for deriving, based on secure session data, the session key to a different server. The device may transmit the secure session data to the server, or to the different server, to re-establish the secure session. The different server may derive, using the information and based on the secure session data, the session key. The different server may re-establish, using the session key, the secure session.
