A tree key graph design scheme for hierarchical multi-group access control

A tree key graph design scheme for hierarchical multi-group access control with low communication overhead is presented. A simulation result shows that the proposed scheme can reduce a communication overhead up to about 15.2% compared to the previously proposed scheme.
