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： 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.

摘要： An information processing apparatus and an information processing method are capable of preventing information from being copied illegally. To put it in detail, a hash function and a service key are stored in advance in an EEPROM of a DVD player serving as a source. In an EEPROM of a personal computer (PC) serving as a sink, on the other hand, its ID and a license key are stored beforehand. The DVD player requests the PC to transmit the ID. The DVD player then applies the hash function to data resulting from concatenation of the ID with the service key to generate a license key (=hash (ID ∥ service-key)). Subsequently, the DVD player generates a source side common session key and encrypts the session key by using the generated license key. Then, the DVD player transmits the encrypted source side common session key to the PC. The PC decrypts the encrypted source side common session key by using the license key stored in its EEPROM to produce a sink side common session key which has a value equal to that of the source side common session key.
