    • The present invention provides a technology of effectively avoiding tracing on a terminal performed with an identification number being a target and DoS attack without making any significant changes to a communication system.In the wireless communication system of the present invention, under a control of a control communication processing portion 113 of an access point, a hash function arithmetic operation processing portion 112 generates a third identification number to be updated using a current identification number, hash key and random number for any wireless communication terminal, a control communication processing portion 113 sends an update instruction signal containing the random number to the wireless communication terminal and updates the current identification number stored in the identification number storage portion 121 to a second identification number. When the wireless communication terminal receives an update instruction signal, the current identification number is updated to the second identification number and the hash function arithmetic operation processing portion generates a third identification number using the current identification number, hash key and random number stored in the self number storage portion.
    • 本发明提供了一种技术,其有效地避免了以标识号为目标和DoS攻击执行的终端上的跟踪,而不对通信系统进行任何显着的改变。 在本发明的无线通信系统中,在接入点的控制通信处理部分113的控制下,散列函数算术运算处理部分112使用当前标识号码,散列密钥和 任意无线通信终端的随机数,控制通信处理部113向无线通信终端发送含有随机数的更新指示信号,将存储在识别号码存储部121中的当前识别号更新为第二识别号。 当无线通信终端接收到更新指示信号时,将当前识别号码更新为第二识别号,并且散列函数算术运算处理部分使用存储在自身中的当前识别号,散列密钥和随机数来生成第三识别号码 号码存储部分。

    • Provided is a photoelectric conversion apparatus for detecting focus, which provides an increased number of ranging points while suppressing a chip-area increase. In a first mode, signals from a first line sensor L1 group are written in a first line memory L1 group while signals from a second line sensor L2 group are written in a second line memory L2 group. In a second mode, signals from the second line sensor L2 group are written in the first line memory L1 group while signals from the first line sensor L1 group are written in the second line memory L2 group, so that even one and the same line sensor can select different ranging point regions, enabling provision of an increased number of ranging points while suppressing a chip-area increase.
    • 提供一种用于检测焦点的光电转换装置,其在抑制芯片面积增加的同时提供了增加的测距点数。 在第一模式中,来自第一行传感器L1组的信号被写入第一行存储器L1组,而来自第二行传感器L2组的信号被写入第二行存储器L2组。 在第二模式中,来自第二线传感器L2组的信号被写入第一行存储器L1组,而来自第一行传感器L1组的信号被写入第二行存储器L2组中,使得即使是同一个线传感器 可以选择不同的测距点区域,使得能够在抑制芯片面积增加的同时提供更多数量的测距点。
