The LCG algorithm is applied to the generation of pseudo random numbers.
$$
X_{n + 1} \equiv (a X_{n} + b) \mod m
$$

The LCG defines three variables——multiplier a, increment b, and modulus m, which decide the generator.

The dp_leakage in RSA attacks, the post will introduce some extensions about the dp_leakage, using the example [2020YCB]Power.

Next part will resolve the [2022MIMIC]cry1 which is more easier than the former wp. The former by using polynomial, the latter by using math deduction with fermat_little_theorem.

Both of them will be given full solutions and comparison.
