ab: Summary: Broadcast encryption schemes are applied to transmit digital
    information of multimedia, software, Pay-TV etc. in public networks. An
    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.
