| 摘 要： | 针对现有单钥-锁对访问控制方案存在严重的溢出问题,基于整数二进制表示的唯一性,提出了一种新的单钥-锁对访问控制方案。新的方案实现简单,除了具有一般单钥-锁对方案的良好动态特性外,还在不需要访问权限递增假设下,实现了用户对文件的多种访问控制权限,并大大减小了溢出问题的发生。

| Abstract: | To overcome the shortcoming of single-key-lock-pair access control scheme at present, a new single-key-lock-pair access control scheme is proposed, based on the property that a integer can be denoted into only one binary digital. All the single-key-lock-pair access control scheme are threaten by overflow problem. Besides that, under old scheme, user can own several kinds of right on one file only based on the supposition that the access rights is increase by degrees. With perfect dynamic feature, the new scheme is simply realized. 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. |
