Abstract: At ICICS 2001, Zou, Ramamurthy, and Magliveras proposed CRTHACS, a chinese remainder theorem based scheme for secure group communication with hierarchical access control. The scheme is designed in such a way that the underlying hierarchy remains hidden from the participating parties/users. This contribution describes several practical attacks on CRTHACS which can reveal significant parts of the hierarchy.
