%X Based on KOR a new rekeying strategy and protocol(called KOR+) are first proposed and compared with KOR in this paper. Then two formulae of the average encryption costs of a key server utilizing KOR+ and UOR are established respectively provided that the key trees are full and balanced. Finally, optimal key tree degrees are deduced analytically for both of them.
