Authenticated group key transfer protocol using secret sharing in MANETS

Implementing group key transfer using secret sharing. We plan on using shamirs secret sharing for key generation and diffie-hellman for key agreement.

there is a key generation center which would provide keys to the group members. In existing system, once a user joins a group, group key for everyone is changed, we want the key to be changed only to the new user. Furthermore the key must be refreshed periodically for everyone as the old key would become redundant after some time.

-The Group key changed is applicable only to the user with new session.

-The group key will be refreshed periodically.

-We use Key establishment protocols.

They are -

2. Key Agreement Protocol- parties agree on a key that influences the outcome.

We are having problems in how to implement this, either using java or using network simulator.
