Access control is one of the mechanisms for data protection in a computer system. Many literaturee besed on cryptography have been proposed to solve the problem of access control in hierarchic structurea. Recently, Liaw and Lei proposed an optimal heuristic algorithm for multilevel data security. Bu

## Recently, Wu and Chang and Shen and Chen separately proposed a cryptographic key assignment scheme for solving access control problem in a partially ordered user hierarchy. However, this paper will show the security leaks inherent in both schemes based on polynomial interpolations. That is, the u
