This paper extends the weak secrecy results of Liu et al. for broadcast channels with two confidential messages to strong secrecy. Our results are based on an extension of the techniques developed by Hou and Kramer on bounding Kullback-Leibler divergence in the context of resolvability and effective secrecy.
