Secure bootstrapping definition
Secure bootstrapping. Means by which security-enabled devices bootstrap trust in the home network when no secure network is in place. This would include secure means to detect devices and authorize them to form a secure home network. Since home networks are likely to use a shared and easily accessi- ble communications medium such as wireless, special care needs to be taken so that adver- saries cannot compromise security at manufac- turing time [13] or when the network is es- tablished. Thus, solutions like that assume ab- sence of an adversary at these times (e.g., [14]) would not be suitable. • Secure join: Means by which a device joins the already established secure home network. This would include detection of the new device and authorizing it to join the existing home network. Also, the newly joined device should not be able to learn anything about the network prior to the time of joining. This property is usually referred to as backward secrecy [15].
