An improved shceme for the old double-way authentication access control scheme based on Harns digital signature is proposed. The new double-way authentication protocol of the improved access control scheme can prevent man-in-the-middle attack and replay attack. After strict formal analysis with BAN logic, the result have proved that the authentication protocol is secure. The improved access control scheme is realized by the mode of single-key-lock-pair. Under new access control scheme, user can own several kinds of access right upon one file under the new scheme without the supposition that the access rights is increase by degrees, and the possibility of overflow problem is significantly reduced by our new method
