    • An apparatus for generating a key for access control of content in a distributed environment network is provided. The apparatus includes a first key distributor configured to generate first encrypted keys by encrypting a first key corresponding to a key for write authorization using each public key of members having write authorization among members included in an access control list including information of at least one user and distribute the access control list and information about access authorization and the first encrypted keys to the members having write authorization, and a second key distributor configured to generate second encrypted keys by encrypting a second key corresponding to a key for read authorization using the first key using each public key of members having read authorization among members included in the access control list and distribute the access control list and second encrypted keys to the members having read authorization.
    • 提供一种用于生成分布式环境网络中的内容的访问控制的密钥的装置。 该装置包括第一密钥分发器,被配置为通过使用包括在包括至少一个用户的信息的访问控制列表中的成员之间具有写入授权的成员的每个公开密钥来加密与用于写入授权的密钥相对应的第一密钥, 将访问控制列表和关于访问授权和第一加密密钥的信息分发给具有写授权的成员,以及第二密钥分发器,被配置为通过使用第一密钥使用第一密钥加密与用于读授权的密钥相对应的第二密钥来生成第二加密密钥 成员的每个公开密钥在包括在访问控制列表中的成员之间具有读取授权,并将访问控制列表和第二加密密钥分发给具有读取授权的成员。
