Authentication in smart micro-grids facilitates circumventing power theft attacks. For economic reasons, we consider a smart micro-grid model in which several users (households) share smart meters. The caveat is that users belonging to neighbouring households can provoke misattribution attacks, resulting in unfair billing. Unfair billing can lead to user distrust in the reliability and dependability of the micro-grid and thus an unwillingness to participate in the scheme. The is undesirable since grid stability is impacted negatively by user withdrawals. In this paper, we make two contributions. First, we propose an attack model for power theft by misattribution. Second, we propose a key management scheme to circumvent such an attack. We show that the proposed scheme is secure against impersonation attacks and performance efficient.
