摘要:: 访问控制是网络中一种重要的安全防护技术。在传统的模糊访问控制中，所评判的用户指标都是由某个确定的值来表示，但是大多数情况下，在用户的评语指标上，属于该指标的某个评语的程度并不能用一个确定的数来表示。针对这一问题，文中通过区间值来表示用户的评语指标，提出了基于区问值模糊访问控制的策略，运用区间值模糊综合评判法分析出用户的访问权限，更好地满足了普适计算环境下访问控制的安全性和实用性。并且通过实例分析表明，基于区间值的模糊访问控制在实际应用中足有效的

Abstract:: On the network,access control is an important security technique. In the traditional fuzzy access control,the evaluation of the users＂ properties is indicated by the determined value. But in most cases, in the users＂ comment index, deterministic is not necessarily a certain number. To address this problem,use interval-valued to represent the users＂ comment index. Propose,based on interval value fuzz- y expression,a new access control strategy. Analyze users＂ access purview which is counted by the interval-valued fuzzy comprehensive evaluation method. This method can better satisfy the secu6ty and practicality in the pervasive computing. And the application instance shows that the interval-valued based fuzzy access control is effective in practice
