Abstract :
A GMH (generalized Merkle-Hellman) cryptosystem is presented, and two theorems are proved to ensure its correctness. The GMH cryptosystem is very suitable for those application domains in which data protection is needed. The authors apply the GMH cryptosystem to access control and obtain a new single-key access control scheme. The data security achieved by the new scheme is very good, and thus it can make the information protection system more reliable. It is shown that, when data security is the most important factor in designing an information protection system, this scheme is the best choice
