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 ...

Random Generator (PRNG) properly using srand() - notice that initialization typically takes the same time on every startup, so just using millis() will probably not result in a good seed. Make sure you contact a NTP time server or have another seriously random input as a seed before ...
