Efficient Group Key Management With Tamper-Resistant ISA Extensions
Source: University of Pitesti
The last decade has seen the enormous increase of group oriented applications many of which use secret group keys to secure the sensitive data transmission among scattered group members across the network or even over the Internet. Many group key management algorithms have been proposed to update these keys when the group changes, preventing information leakage prior to and after the change. Simple solutions such as updating new keys through point-to-point channels are inefficient and tend to incur large communication and computation overhead.
