摘要：Distributed computing gives an adaptable and convenient route for information sharing, which bringsdifferent advantages for both the general public and people. In any case, there exists a characteristic resistance forclients to specifically outsource the shared information to the cloud server since the information frequently containssignificant data. In this manner, it is important to put cryptographically upgraded get to control on the commoninformation. Identity based encryption is a promising crypto graphical primitive to build a practical information sharingframework. However, access control is not static. That is, the point at which some client's approval is expired; thereshould be an instrument that can remove him/her from the framework. Thus, the revoked client can't access to both thepreviously and therefore shared information. To this end, we propose an idea called revocable-storage identity basedencryption (RS-IBE), which can give the forward/backward security of cipher content by presenting the functionalitiesof client revocation and cipher content upgrade at the same time. Moreover, we display a solid development of RS-IBE,and demonstrate its security in the characterized security show. The execution correlations show that the proposed RSIBEscheme has advantages in terms of functionality and efficiency, and thus is feasible for a practical and costeffectivedata-sharing system. Finally, we provide implementation results of the proposed scheme to demonstrate itspracticability.
