    • An information processing apparatus has an authentication/key exchange unit, a round trip time measuring unit, a common key transmitter, a contents key transmitter and a contents transmitter. The round trip time measuring unit sends a round trip time measuring request generated to the communication apparatus through the first communication connection to measure the round trip time, and check whether the measured round trip time is within a predetermined time and whether a transmitting source of the round trip request response is the communication apparatus sharing the first key. The common key transmitter encrypts a second key used for contents transmission by using the first key and transmits the encrypted second key through the first communication connection when the round trip time measuring unit succeeds in the checking. The contents transmitter encrypts the contents requested by the communication apparatus by using the second key and sends the encrypted contents to the communication apparatus through the second communication connection.
    • 信息处理装置具有认证/密钥交换单元,往返时间测量单元,公共密钥发送器,内容密钥发送器和内容发送器。 往返时间测量单元通过第一通信连接向通信装置发送生成的往返时间测量请求,以测量往返时间,并检查测量的往返时间是否在预定时间内,以及是否发送源 往返请求响应是共享第一个密钥的通信设备。 公共密钥发送器通过使用第一密钥加密用于内容传输的第二密钥,并且当往返时间测量单元成功检查时通过第一通信连接发送加密的第二密钥。 内容发送器使用第二密钥加密由通信装置请求的内容,并通过第二通信连接将加密的内容发送到通信装置。
