A Policy-based Authorization Scheme for Resource Sharing in Pervasive Environments

摘要: Ubiquitous environments require special properties that traditional computing does not support. The high diversity of mobile devices and the marked rise in ubiquitous resources have originated a great variety challenges such as proper resource management which plays fundamental role pervasive computing, where adaptation dynamic re-configuration take place. In previous works [MoGi08], [MoOG10] we presented CARM (Composable-Adaptive Resource Management), new adaptive approach supports for required resources. constitutes component-based model to abstract system’s transparent uniform way applications. Due its network heterogeneity population nomadic users, important security arise; therefore, this article address CARM’s primary concerns towards development “Security module” capable certifying eligibility join personal without compromising privacy. Our is analyzed terms Authentication Authorization, essentially consisting an authorization scheme using Attribute Certificates (ACs) supported by control policies define all decisions needed among unknown devices. This paper mainly describes ongoing work proof-of-concept implementation given scenarios; initially considering two enabled mobile-phones with Bluetooth connectivity enforcing altering bandwidth efficiency.
