3.1.1. Confidentiality

Home appliances send their energy detail to aggregator, SM or SP. This detail may reflect a users' personal profile. Privacy and confidentiality are interdependent of each

other [45]. By securing messages from unauthorized access, privacy of home incumbents will be retained. If privacy of home users is compromised, then confidentiality is automatically violated. To ensure confidentiality, various schemes for HAN are employed, e.g., homomorphic encryption, blind signature, in-network aggregation, etc. [16,21].
