    • According to an embodiment, a tracking drive type solar power generation apparatus (1) includes a tracking control portion (20) having a tilt drive portion (21) that controls the tilt position of a module panel (10) (a driving solar cell module (12) and juxtaposition solar cell modules (13) supported by main beam members 22), a swivel drive portion (25) that controls the swivel position of the module panel (10), and a tracking control base (20c) to which the tilt drive portion (21) and the swivel drive portion (25) are integrally connected. The driving solar cell module (12) includes, in a middle thereof in a length direction, inside a bottom plate portion (14b) thereof, a tilt drive housing portion (17) in which the tilt drive portion (21) is housed. A tilt rotation axis (21s) serving as the center of rotation of the tilt drive portion (21) is disposed on the same side with respect to the bottom plate portion (14b) as the center of gravity (CG) of the driving solar cell module (12).

    • Disclosed is a key generator, which assures the security of a key by preventing a circuit designer and other persons from readily knowing the value of the key. Random number generator circuits (51, 52, 53 and so on) generate random numbers respectively in accordance with different clocks (CLK1, CLK2, CLK3, and so on). An arithmetic circuit (59) operates on the random numbers generated from the random number generator circuits (51, 52, 53 and so on) to generate an N-bit random number RA as the output from a random number generator (50). This N-bit random number is RA acquired via a key selector (43), and latched into a key register (45) in accordance with an acquisition enable signal EN from a timing monitoring counter (47), which is driven by a clock CLKA other than clocks CLK1, CLK2, CLK3, and so on, to obtain a hardware key, which is a unique secret key.
    • 公开了一种密钥生成器,其通过防止电路设计者和其他人容易地知道密钥的值来确保密钥的安全性。 随机数发生器电路(51,52,53等)根据不同的时钟(CLK 1,CLK 2,CLK 3等)分别产生随机数。 运算电路(59)对从随机数生成电路(51,52,53等)生成的随机数进行运算,生成作为随机数发生器(50)的输出的N位随机数RA。 该N位随机数是通过密钥选择器(43)获得的RA,并根据来自定时监视计数器(47)的获取使能信号EN锁存在键寄存器(45)中,定时监视计数器由时钟CLKA 除了时钟CLK 1,CLK 2,CLK 3等之外,以获得作为唯一秘密密钥的硬件密钥。
