    • According to one embodiment, the data transmitting device includes a storing unit, an authenticator generating unit, and a communication unit. The storing unit stores accuracy information based on an accuracy of synchronization between a first clock and a second clock. The first clock indicates a current time of the data transmitting device. The second clock indicates a current time of other device to be a destination of a data packet. The authenticator generating unit calculates a first time by adding a predetermined time to the current time of the data transmitting device, calculates a second time by adjusting the first time using the accuracy information, and generates an authenticator using the second time, the data packet, and a predetermined secret key. The communication unit transmits, to the other device, the data packet with the authenticator at a third time obtained by adding the second time to a predetermined time.
    • 根据一个实施例,数据发送装置包括存储单元,认证器生成单元和通信单元。 存储单元基于第一时钟和第二时钟之间的同步精度来存储精度信息。 第一个时钟表示数据发送设备的当前时间。 第二个时钟表示其他设备当前是数据包目的地的时间。 认证器生成单元通过将预定时间与数据发送装置的当前时间相加来计算第一次,通过使用精度信息调整第一次来计算第二次,并且使用第二次生成数据包, 和预定的秘密密钥。 通信单元将通过将第二时间添加到预定时间而获得的第三时间向认证器发送与另一设备的数据分组。
