I need to program a system composed by a centralized server and many clients. 1. The server maintains a list of an authenticated clients. (I will let you know protocol that u can use). 2. Each client can initiate a multicast group communication session by selecting a subset of the connected and authenticated clients. 3. For each session, the server generates a secret key and distributes it to the group members. 4. Each group member send his encrypted messages to the centralized server which multicast them to the other group members. 5. Authentication and Integrity of messages must be satisfied. I need to design and implement this system by using java sockets and Java Cryptographic Extension. I need it done within 2 days. Please only bid if you are familiar with these things can finish it within time. I need commented code. I have done most of it and it needs to add encryption part.
