The availability of individual load curves per household in the smart grid end-user domain combined with nonintrusive load monitoring to infer personal data from these load curves has led to privacy concerns. Two types of approaches show high potential to resolve this issue: secure aggregation and multi-resolution representation with conditional access. In this paper a combination of these two principle approaches is proposed. It is shown formally that secure aggregation and wavelet-based multi-resolution representation are compatible.
