An effective access control mechanism in home network environment based on SPKI certificates

In home network environment, security is one of the most important issues that need to be addressed because the services provided by all kinds of household appliances are likely related with the privacy information of the residents. Although several access control mechanisms have been proposed in the last few years, these existing models always preserve all the access control policies in the home gateway or the distributed household appliances, and all of them have conspicuous defects. In this paper, we divide access control policies into general policies and privacy policies according to different security requirements of the residents. With the help of SPKI certificates theory, we demonstrate that our model is an effective access control mechanism by providing two types of access control policies with different security schemes.
