A group key distribution protocol can enable members of a group to share a secret group key and use it for secret communications. The researchers proposed an authenticated group key distribution protocol using polynomial-based secret sharing scheme. Recently, Guo and Chang proposed a similar protocol based on the generalized Chinese remainder theorem. In this paper, the authors point out that there are some security problems of Guo and Chang's protocol and propose a simpler authenticated group key distribution protocol based on the Chinese remainder theorem.
