PROJECT TITLE :

Reducing rekeying time using an integrated group key agreement scheme

ABSTRACT:

With the necessity for providing multiple levels of access control for group members, several group key management schemes designed for hierarchical access control are place forward. However, most of these schemes target the potency of group key establishment and rekeying in centralized environments. This paper proposes an integrated group key agreement (IGK) scheme for contributory environments. The IGK theme employs the integrated key graph to remove key redundancies existing in single key trees, and reduces key establishment and rekeying time whereas providing hierarchical access management. Performance analyses and simulations conducted with respect to computation and communication overheads indicate that our proposed IGK scheme is more efficient than the freelance cluster key agreement theme.
