In the multimedia applications messages like audio and video messages are broadcasted through groups. To provide secrecy of those keys which are used in this communication, the methods like key generation and the key distribution among these groups should be done in a secure way. The problems due to this are mutual authentication with the exchange of a session key. In most of the Key Management schemes, different types of group users obtain a new distributed multicast group key which is issued for encrypting and decrypting multimedia data for every session update. Among the various works on key distribution, The RSA method focuses on making the key generation operation speed and also reduces the complexity.
