Abstract: 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.

Abstract: A system encrypts a name of content stored in a node of a hierarchical structure. A content receiving node encrypts a name of a predetermined node among names of nodes included in a content name, such as by using a hash function, and transmits the encrypted content name to receive the stored content. A relay node receives the content name including the encrypted name of the node and decrypts the encrypted name of the node, such as by using a reference table. The relay node uses the decrypted node name to relay the content request to the content storage node. Since the content name is encrypted, content routing may be performed without disclosing information associated with a hierarchical structure in which the content is stored.

Abstract translation: 系统加密存储在层次结构的节点中的内容的名称。 内容接收节点例如通过使用散列函数来加密包含在内容名称中的节点的名称中的预定节点的名称，并发送加密的内容名称以接收所存储的内容。 中继节点接收包括节点的加密名称的内容名称，并且通过使用参考表来解密节点的加密名称。 中继节点使用解密的节点名称将内容请求中继到内容存储节点。 由于内容名称被加密，可以执行内容路由，而不会公开与其中存储内容的分层结构相关联的信息。
