Abstract
A security key is configured to be replaced when a device is replaced in a machine-to-machine (M2M) system. A method for operating a first device may include: receiving a first message including first information associated with security key replacement from a second device or a third device; receiving a third message including second information associated with security key replacement, which is generated based on a second message including a security key replacement indication, from the second device or the third device; and replacing the security key.
