Security and scalability are important issues for secure group communication in a grid environment. Secure communication involves confidentiality and authenticity of the user and the message between group members. To transmit data in a secure way, a secure and authenticated key transfer protocol should be applied. Key transfer protocol needs an entity responsible for user authentication and secures session keys. Recently, many researchers have proposed secure group communication methods based upon various cryptographic techniques. In this paper, we propose a secure key transfer protocol that uses the concepts of soft dipole representation of the image and steganography to establish secure communication between group of authenticated users. Steganography hides the existence of group keys in images. This protocol is more secure as compare to previously proposed encryption based group communication protocols. This protocol uses a centralized entity key management center (KMC). KMC generates the group key using soft dipoles of the images of the group members and broadcast it securely to all the communicating group members.
