However, the algorithm being used on Arduino to make random number generator function cannot ensure the randomness of the challenge value, thus this paper will propose another algorithm to be used as challenge value that can cover the weakness mentioned. The proposed algorithm is actually one of stream cipher standards, which is ...

Arduino 中的random()函数基于线性同余生成器（Linear Congruential Generator, LCG）算法。线性同余生成器是一种产生伪随机数的算法，其基本公式为：Xn+1 =(aXn+c)modm 其中：Xn是当前的随机数种子（初始值或上一次生成的随机数）。a是乘数（multiplier）。c是增量（increment）。m是模数（modulus）。Xn+1是下一...
First, I looked at some results from an existing random number generator. In my case, I chose the famous random.org. I generated three sets of 10,000 random bytes:The graph looks well distributed and the average standard deviation is 74.1. The height of the graph fits within 20 to 60 ...

float getDutyCycle() returns the set (clipped) duty cycle. void setRandomSeed(uint32_t a, uint32_t b = 314159265) sets the initial seeds for the (Marsaglia) random number generator. The first is mandatory, the second is optional.Wave...

To generate a random background color, I use a pseudo-random number generator to generate random RGB values and I assign the resulting color to a new Brush object. We must use Dispatcher.Invoke() to make changes to the UI thread, because the thread triggered by the event handler does not...
