Group Key Management Based on T-OFT
>A novel group key management protocol based on Ternary Tree and One-way Function (T-OFT) is proposed in this paper to avoid the problem about forward confidentiality, backward confidentiality and conspiracy attack. The ternary tree is used in the protocol which reduces the number of storing keys and lowers the cost of storage and communication. We also use TPM to generate and store keys to ensure no keys outside plainly, guaranteeing absolute security of keys. The group key will be renewed when group members join or quit in order to provide a safe key management module. The protocol overcomes the above defects and lowers the cost of storage and communication, and could guarantee the physical security of the key server.
