摘要： To securely transmit content through remote access via an external network, such as a WAN, while exceeding restrictions of an RTT and a TTL.A way of handling a flag for controlling remote access of content is explicitly defined, and an authentication method is explicitly defined when a content using device performs remote access. Thus, also in remote access, similarly to access of the related art in a household, a copyright protection environment of content based on the DTCP-IP is constructed.

摘要： Content is transmitted within a range of the user's legitimate use while limiting the number of equipment to which the content is transmitted at the same time.A content using apparatus periodically transmits an exchange key and the corresponding key ID using a command. Only while receiving the key ID at predetermined reception cycles, a content providing apparatus maintains the corresponding exchange key. When not periodically receiving the key ID, the content providing apparatus destroys the corresponding exchange key. After that, when receiving a command including the key ID, the content providing apparatus returns a response including information indicating that the exchange key has become invalid.
摘要翻译：内容在用户合法使用的范围内传输，同时限制同时发送内容的设备数量。内容使用装置使用命令周期性地发送交换密钥和对应的密钥ID。只有在预定的接收周期接收到密钥ID，内容提供装置才保持相应的交换密钥。当不定期接收密钥ID时，内容提供装置破坏对应的交换密钥。之后，当接收到包含密钥ID的命令时，内容提供装置返回包含表示交换密钥变得无效的信息的响应。

摘要： A measurement to obtain an RTT to a receiving apparatus is performed by a relay apparatus that is disposed between a WAN and a home network and connects these two networks. That an RTT value is equal to or less than the threshold value is set as a content distribution condition from a transmitting apparatus, so that the same use environment as a system using current DLNA and DTCP-IP can be realized for content use in the home network. Thereby, unjust distribution of content is prevented while an authentication and key exchange procedure performed via an external network is allowed.
摘要翻译：通过设置在WAN和家庭网络之间的中继设备来执行向接收设备获得RTT的测量，并且连接这两个网络。 RTT值等于或小于阈值被设置为来自发送装置的内容分发条件，使得可以实现与使用当前DLNA和DTCP-IP的系统相同的使用环境用于家庭中的内容使用网络。由此，在通过外部网络进行认证和密钥交换过程被允许时，防止内容的不正当分配。

摘要： In view of the fact that devices connected on a home network are located in home, that is, at close range and therefore a user can physically access the devices within a relatively short period of time, identifying whether or not a home server for distributing the contents and a client terminal using the contents are connected to the same home network based on whether or not they can share access to the same physical medium within a short period of time. The authenticity of devices connected on a home network connected to an external network via a router is authenticated.

摘要： The construction of a receiving apparatus for receiving a broadcast from a plurality of broadcasting providers is simplified. In a receiving apparatus for receiving a broadcast from a plurality of broadcasting providers, of the function blocks which constitute the receiving apparatus, a block used in common irrespective of the broadcasting provider is formed as a common block, and a block different from one broadcasting provider to another is formed as an independent block. These blocks are connected to each other through an IEEE1394 interface, and the common block is shared among the plurality of blocks which are not used in common, so that a receiving process is performed.

摘要： In order to limit use of content, when a source receives a request for transmitting content from a sink, the source performs an authentication process. When the authentication is successful, the source transmits to the sink key information necessary for decrypting the encryption applied to the content. The sink can receive the content by receiving the key information and by decrypting the encryption applied to the content by using the key information.

摘要： A content usage control apparatus prevents a content managed by an end user from being illegally used. To prevent a content from being used by an apparatus or user other than an authorized apparatus or user, a content usage control apparatus registers the authorized apparatus or user and determines, before providing the content, whether the content is going to be provided to the authorized apparatus or user. The content usage control apparatus also has the capability of imposing a limitation on rewriting of registration. The above-described capabilities of the content usage control apparatus make it possible to protect copyright of information to be provided. A specific example of the content usage control apparatus is a server which stores contents such as movie contents or music contents, and may be used in a system in which a content is provided in response to a request from a client such as a portable telephone, a TV set, or a personal computer, connected to the server.

摘要： An information processing apparatus allowing proper communication with a communication partner in accordance with a communication time of the communication partner. A reception control unit receives a random challenge (RC) from a transmission terminal and supplies it to a generation unit. The reception control unit transmits an RC reception message indicating an RC reception to a transmission side. The generation unit executes a Hash process relative to RC and supplies resultant authentication data to a generation unit. A transmission control unit controls the generation unit at a timing before a response request command from the transmission side is received, to make the generation unit generate a response message containing authentication data corresponding to the response request command, and when the response request command is received, transmits the response message to a transmission destination terminal. The apparatus is applicable to a content providing system.
