Abstract
A system, method, and owner node for securely changing a mobile device from an old owner to a new owner, or from an old operator network to a new operator network. The old owner initiates the change of owner or operator. The old owner or operator then commands the mobile device to change a currently active first key to a second key. The second key is then transferred to the new owner or operator. The new owner or operator then commands the mobile device to change the second key to a third key for use between the mobile device and the new owner or operator. Upon completion of the change, the new owner or operator does not know the first key in use before the change, and the old owner does not know the third key in use after the change.
