Abstract
In one implementation, actions may include generating a first key for encryption of data and a second key for encryption of connection parameters. The connection parameters may enable the client device to establish a connection to an update server. Further actions may include encrypting the connection parameters using the second key and providing the first key and the second key to the update server. Additional actions may include storing the first key on the client device, receiving, at the client device, a notification of an update that includes the second key, decrypting the encrypted connection parameters using the received second key, and connecting to the update server using the decrypted connection parameters. Actions may further include providing a request for the update to the update server, receiving data encrypted using the first key in response, and decrypting the encrypted data using the first key.
