An Efficient Transmission over Cooperative Groups Using Hybrid Scheme

K.Banupriya

The growth of group applications triggers the need for group-oriented security mechanisms over insecure network channels. The applications include IP telephony, collaborative work spaces, secure conferences, as well as dynamic coalitions common in law enforcement and disaster rescue scenarios. Standard security services required in such group settings, e.g., confidentiality of group-wide broadcasts can be very efficiently achieved if all group members share a group-wide secret key. The existing key management system used two approaches. One is Group key Agreement and another one is Key Distribution. Both approaches provided an unsecured data transmission and also very difficult to join a member in a remote system. It cannot deals with re-keying concept. In this paper, I proposed Hybrid of Group key agreement and public key broadcast encryption to Effective and Secure transmission of data to the remote cooperative groups. It provides fully secure data transmission and easy to join a new member in the existing system. In this approach, update the session key in a group easy.
