Genius "Not only do not understand romance (turn)

Recently popular a joke called "Genius Love": On the bus, a pair of lovers affectionate, sweet talk. Man: "Dear, I love you ~" Woman: "Me too!" And my love is twice as much as yours! "Man:" Wow! Then I will be your three times times! "Genius:" Hum. The male and female love is x and y respectively, the equation y=2x,x=3y, the solution is x=y=0. ”
It seems genius children's shoes do not understand romantic, or envy others show love, so want to let people die quickly. This genius will be split into different dimensions to ^o^
In addition, the genius has a structural flaw in knowledge. Obviously, the above equation is only x=y=0 in the real number field, but this is also the level of high school mathematics. In the computer professional mixed for 4 years of the school slag, as long as the knowledge of finite fields, the above embarrassing can be broken.
What is a finite field? According to the Wikipedia definition: A field with a finite number of elements is called a finite field. So what is a domain? In abstract algebra, a field is an algebraic structure that can be added, minus, multiplied, and removed (except by dividing by 0). The concept of domain is the generalization of several fields and arithmetic. "The domain satisfies certain properties, such as addition, the exchange rate of multiplication, the binding law, and the binding law of multiplication to addition."
Well, no one cares about the concept. Let's see the actual combat. According to the definition of finite field, the Natural number field is 5 modulo (God horse? Do not know modulo operation? Well, that's the remainder), and the result is a finite field. To make this field a GF (5), then the X+y on GF (5) is equivalent to the x*y on the X+y mod 5,GF (5) on the natural number field n = x*y mod 5 on N. Subtraction and division are the inverse of addition and multiplication.
Back to this topic, if x = 4,y = 3, then 2x = 8 MoD 5 = 3,3y = 9 MoD 5 = 4, so sister paper Love is Han paper twice times, Han paper love is sister paper three times times, young couple show loving success, genius solitary pillow sleepless.
Finite fields have very important applications in cryptography. The famous RSA algorithm uses the domain GF (P) with the prime number as the model. Children's shoes interested in cryptography be sure not to do such a poor genius.
Of course, the arithmetic in abstract algebra can be quite different from the arithmetic of several fields. For example, in binary polynomial domain GF (2^m), where each element is a binary polynomial, its arithmetic definition is not the same as the number of fields, but also satisfies the nature of the domain. Both GF (P) and GF (2^M) can be used for elliptic curve encryption algorithms. God horse? You don't know the elliptic curve encryption algorithm? The serial number that Microsoft started with Windows XP was made with this algorithm!
In addition, the finite field is also known as Gamma Rovanic (Galois Filed, abbreviated GF, not a girlfriend's meaning oh), named after the untimely death of the famous two-force mathematician Gamma MabThera, said he was two, because he died in the duel at the age of 21.
