Access control is a fundamental concern in any system that manages resource. In particular, the dynamical distributed access control problem is very difficult and does not have easy solutions. In this paper, we provide solutions by limiting the problem's domain and propose a simple, yet efficient dynamic hierarchical access control schemes: a Chinese Remainder Theorem based hierarchical access scheme for secure group communications. We also propose an improved scheme for recent attacks
