摘要：Vehicle safety related applications which are drawing increasing attention in public have attracted extensive research both in academic and industry areas. However, it is assumed that one service is offered by one provider, thus forcing vehicle drivers to subscribe to several service providers within limited computation capabilities. In this paper, we present a fine-grained privacy preserving protocol over attribute access control for VANETs which allows a service provider to offer a range of safety related services to vehicle drivers. The vehicles which have appropriate service attributes are autho- rized to access the requested services. In order for a vehicle to access to the authorized services, we propose a fined-grained access control mechanism based on linear secret sharing scheme. We con- sider the concept of an ID-based signature, an attribute based encryption (ABE) and a linear secret sharing scheme (LSSS) as our building blocks
