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...
The reading from analogRead has been a staple as a seed for the Arduino built-in pseudo-random number generator. It usually goes like this:randomSeed( analogRead(A0) ); long randNumber = random(10, 10000); Serial.println(randNumber); ...

I used the code above and found that no matter what seed number I use the numbers are not repeatable, upon further research I found that the ESP32 has a true-random number generator by using the noise values on the WiFi/BLE chip, so that explains it. This is one of the rare occurren...
Pseudo-random number generators are found in both hardware and software implementations, with Field Programmable Gate Array (FPGA) and microcontroller-based implementations utilizing platforms such as Arduino and Raspberry Pi. Encryption applications primarily focus on image ciphering, with only a few ...
Possible limitations of the proposed study include the randomness range of the generated random switching signals for different modulation schemes using an Arduino Due board. The accuracy and randomness range of the random number generator along with the frequency of the switching signal could be improv...
I chose an Arduino Mega 2560 as microcontroller because I needed many I/O ports. Below is a picture of a preliminary state. It took me some experimenting and I even disassembled the keyboard partially to get a proper understanding of the pin out etc. On the Internet, the maintenance manual...
