Establishing secure and efficient encrypted connectivity for random cloud tenants

In cloud computing, the cloud participants join in or leave the network, and launch on-demand secure communication randomly. In such situations, KDC and PKI infrastructure are very low efficiency and costly. In order to establish secure and efficient encrypted connectivity for random on-demand cloud tenants, some important topics should be considered and solved firstly, such as secret agreement, sharing and session key establishment. In this paper, a secret sharing scheme is proposed for cloud tenants in cloud computing when any two of them launch on-demand encrypted connectivity, for the application of the proposed secret sharing scheme, we construct the symmetric key application in cloud computing environment. Analysis and simulation of the proposed scheme demonstrate that it is secure and efficient to establish encrypted connectivity for random on-demand network participants for cloud computing.
