摘要： According to an aspect of the present invention, there is provided a data transmitting apparatus including an authenticator generating unit and a communicating unit. The authenticator generating unit generates a first authenticator by using a first encryption key and generates a second authenticator including a first to an n-th fragment information items by using a second encryption key. The communicating unit transmits a first packet including the first authenticator and the first fragment information item to a destination device and, after the first packet is transmitted, if a response indicating successful authentication is not received from the destination device within a certain period, sequentially transmits an i-th packet (i is an integer being 2 or more and n or less) including the i-th fragment information item to the destination device.
摘要翻译：根据本发明的一个方面，提供了一种包括认证器生成单元和通信单元的数据发送装置。认证器生成单元通过使用第一加密密钥生成第一认证器，并且通过使用第二加密密钥生成包括第一至第n片段信息项的第二认证器。通信单元将包含第一认证器和第一分段信息项的第一分组发送到目的设备，并且在发送第一分组之后，如果在一定时间段内没有从目的地设备接收到指示成功认证的响应，则顺序发送第i个分组（i是2以上且n以下的整数）包括到目的设备的第i个分段信息项。
