An MTA certificate containing a public key is provided to a provisioning server, typically via an MIB. The provisioning server retrieves configuration information associated with the MTA. A symmetric session key is randomly generated and used to encrypt the configuration information. The public key is used to encrypt the symmetric key. The encrypted session key is combined with the encrypted configuration information into a composite file, and the composite file is distributed to the device that contains the MTA. The MTA device decrypts the session key using its private key that corresponds to the public key and the decrypted session key is used to decrypt the configuration information. The decrypted configuration information is used to complete initialization of the MTA device.
