Abstract

In this paper, we analyse the security of a cryptographic key assignment scheme, recently proposed by Huang and Chang, that is designed to provide time-constrained hierarchical access control. We show that the new scheme has potential security vulnerabilities, which enable malicious users and attackers to violate the privacy of other users.
