In Cloud computing environment, resources include virtual machine, CPU and Storage. These resources are accessed by tenants. Group key may be used to access the resources securely. Group key is constructed using tree by considering tenants in a group. In existing scenario, different key trees are formed even if tenants are common among multiple groups to access the resources. This paper addresses the issues of overlapping tenants that accesses resources. If there are overlapping members in multiple groups, combined key trees may be formed. Through the analysis, it is observed that computational overhead is decreased by 24% if we combine the key trees than the separate key trees. It is also observed that key establishment time for combined key trees is less compared to separate key trees.
