In this project we studied tradeoffs between efficiency and security in group key management for multicast communication. Efficiency is judged in terms of group rekeying and key storage cost; security is judged in terms of backward secrecy, forward secrecy and resistance to collusion. Group key management schemes that support fine-tuning the tradeoff between security and efficiency can be used in a wide range of applications, and have the ability to adapt to e.g. changes in number of peers or security requirements.
