3.1.3. Anonymity

Anonymity refers to the situation where the real identity of a person is kept secret. During sharing of secret control signals or reading, a device may protect their real identity from other appliances or devices [47]. Even an appliance or SM cannot recognize other devices communicating with them in a HAN. The purpose of anonymity is to hide one's identity from appliance to appliance, appliance to SM, SM to SP, and SP to appliance. Various techniques for anonymity include PALK, ASF, and TAI [48,49].
