一种普适计算下的访问控制策略

An Access Control Scheme for Pervasive Computing

计算技术的发展是以为人类服务为目标的,需要一种"以人为本"的计算模式,而普适计算正是这样的一种革新性的计算模式。访问控制作为一种重要的安全措施在系统安全中得到了广泛应用,而普适计算模式下的系统安全也需要一种合适的访问控制策略。为此,比较了现有访问控制模型的各自特点和适用范围,分析了普适计算环境下访问控制策略的特殊要求,在此基础上详细描述了普适计算模式下动态访问控制策略实现方法。并在ARM7嵌入式实验箱现有资源基础上模拟了普适环境下考虑上下文信息的访问控制中的部分机制。

The development of computing science is to serve human,so it needs a people centered computing paradigm,and ubiquitous computing breeds as such an innovatory computing model.Access control is widely applied to system security as an important safety precaution,and system security in pervasive computing likewise needs an appropriate strategy.For that purpose,compare the characteristics and application scope of the existing access control models,analyze the special access control policy requirements in pervasive environments.On these bases,give a minute description on implementation method of dynamic access of pervasive computing.And simulated part of the dynamic access control mechanism in pervasive computing using available resources of ARM7 embedded experimental box.
