: Originality: This paper extends our earlier extended abstract [CitationRef removed]. The earlier abstract introduces a new security model and construction of multi-cast key distribution (MKD). This submission adds following new results: 1. Though the earlier abstract does not give the security proof of the proposed scheme, we show the security proof formally. 2. In the earlier abstract, the proposed MKD scheme only captures a simple setting (i.e. only one user joins/leaves the group simultaneously) because of simplicity, and it is just described that an extension to the general setting will be possible. In this paper, we give a concrete protocol of MKD in the general setting (i.e. multiple users can join/leave the group simultaneously). This manuscript is the authors’ original work and has not been published nor has it been submitted simultaneously elsewhere.
