IBE system based on trust service

The existing IBE system can avoid the problems of PKI,but in practical application it is lacking of identity management,authority management and key management,while it can not resolve the cross-domain interoperability.In this paper,we designed a new scheme: IBE system based on trust service,through add four mechanisms to the existing system to complete the system.The architecture and mechanism of the new scheme is introduced.This scheme validates the superiority of high security,high efficiency and low cost compared with PKI.
