EncryptionAlgorithmRSA Algorithm
It is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. The algorithm is named by the inventor Ron Rivest, Adi Shamir, and Leonard Adleman. However, the security of RSA has never been proved theoretically. It has experienced various attacks and has not been completely cracked yet.

to serialize the model under the specified directory.
After saving to the Saved_model_dir directory, there will be a SAVED_MODEL.PB file and a variables folder. As the name implies, variables saves all variables, SAVED_MODEL.PB is used to save information such as the structure of the model.
Gta5-InThe model can be loaded using the Tf.saved_model.loader.load method. Such as

Steps:Randomly select two large prime numbers p and q,p not equal to Q, calculate N=PQ.According to Euler function, r= (p-1) (q-1) is obtained.Select an integer w that is less than R and Coprime, and obtain a modulo inverse of w about modulo R, named D. (DW mod n = 1).The records of P and Q are destroyed.Public key: N, WPrivate key: N, D

, when the side length is (a, B), a total of (N'-a) * (N'-B) * (gcd (a, B)-1) is invalid. However, because the range of N is too large, the length of the enumeration side is O (n ^ 2) Time-out. Therefore, we need to optimize the solution process:
The specific method is to enumerate the GCD value. Because the GCD value is at least 2, it will affect the result. Therefore, the GCD value can be enumerated from 2 and the maximum GCD value is n. If the enumerated GCD value is K, then if there is gcd

) ^ 2 = n ^ 2 + 2n + 1, (n + 1) ^ 2 and N ^ 2 are the two workers we are looking. The following shows that this solution is unique. If the prime number P can be expressed as a ^ 2-B ^ 2, P = a ^ 2-B ^ 2 = (a + B) (a-B ). Since P is a prime number, only a + B = P and a-B = 1 are possible. This gives the unique solutions of A and B.
4. When n is an integer greater than 2, if one of the numbers 2 ^ n + 1 and 2 ^ N-1 is a prime number, the other must be a union.Proof: 2 ^ n cannot be divisible by 3.

It can be found that there is always a number x, which satisfies ax≡1 (mod n).The smallest positive integer x that ax≡1 (mod n) satisfies is called the order (or number) of a-modulo n, which is recorded as ENA (some places do Ordna).How do you understand it? You have to keep calculating a,a2,a3, ..., (note to modulo n) we know that, according to the pigeon Nest principle, there
