In this paper, the completely stealthy attack design against exposed sensor nodes and channels is investigated. The objective is to develop a stealthy attack strategy based on the connectivity among nodes and channels. To this end, the concept of exposed nodes is introduced, and the necessary and sufficient conditions for achieving completely stealthy attacks via exposed nodes are established. Furthermore, an energy cost is assigned to both nodes and communication channels. To minimise the required attack energy, an improved simulated annealing algorithm is proposed. Finally, two simulation examples are provided to verify the effectiveness of the proposed schemes.
