Broadcast encryption schemes are applied to transmit digital information of multimedia, software, Pay-TV etc. in public network. Important thing is that only user who is permitted before only must be able to get digital information in broadcast encryption schemes. If broadcast message transfers, users who authority is get digital information to use private key given in the advance by oneself. Thus, user acquires message or session key to use key that broadcaster transmits, broadcaster need process that generation and distribution key in these process. Also, user secession new when join efficient key renewal need. In this paper, introduce about efficient key generation and distribution, key renewal method. Take advantage of two technique of proposal system. One is method that server creates key forecasting user without user’s agreement, and another is method that server and user agree each other and create key. Advantage of two proposal system because uses a secret key broadcast message decryption do can and renewal is available effectively using one information whatever key renewal later.
