摘要

本文基于Lagrange插值多项式

提出了等级系统中的一个访问控制方案

并从空间复杂度和时间复杂度角度分析了其性能.该方案具有很强的安全性

并且允许所有用户自主选择秘密密钥.提出了基于门限秘密共享体制的一般性访问控制方案

阐述了一般性的访问控制方案的基本思想、方案的构造算法及安全性.

Abstract

Access control is the key problem in a hierarchy system.An access control scheme based on Lagrange's interpolation polynomial is proposed

and the property is analyzed from the view of time and space complexity.The scheme is of very strong security

and it allows all users to select their own secret keys.A general access control scheme in a hierarchy is proposed based on threshold secret sharing scheme.Its basic idea

constructing algorithm and security are discussed.
