Key Trees Combining Algorithm for Overlapping Resource Access Members
Amar Buchade, Rajesh Ingle · International journal of network security · 2016
In cloud computing environment, resources are accessed by multiple members. Resources may be considered as VM, CPU, Storage etc. Group key management required when multiple members in group accesses the resources securely. In existing group key management, separate key trees are formed even if members are common in another group to access the resources. The solution to this is to form the combined key trees for resources which contain- ing overlapping members. Through the analysis it is ob- served that computational overhead is decreased by 22% if we combine the key trees than separate key trees for each resource.
