主　　题：location-based service location privacy attribute-based encryption 

摘      要：Unauthorized access to location information in location-based service is one of the most critical security threats to mobile *** order to solve the problem of quality of location sharing while keeping privacy preserved,adaptive privacy preserved location sharing scheme called APPLSS is proposed,which is based on a new hierarchical ciphertext-policy attribute-based encryption *** the algorithm,attribute authority sets the attribute vector according to the attribute tags of registration from the location service *** the attribute vector can be adaptively transformed into an access structure to control the encryption and *** APPLSS offers a natural hierarchical mechanism in protecting location information when partially sharing it in mobile *** allows service providers access to end user’s sensitive location more flexibly,and satisfies a sufficient-but-no-more *** end-users,the quality of service is obtained while no extra location privacy is *** improve service response performance,outsourced decryption is deployed to avoid the bottlenecks of the service providers and location information *** performance analysis and experiments show that APPLSS is an efficient and practical location sharing scheme.
