有限域上逆运算是密码学中常用的运算。本程序提供有效、快速的有限域上逆运算程序解决求逆问题。-The inversion operation of a finite field is commonly used in cryptography operations. The program provides effective, fast algorithm and program for computing the inverse problem in the finite field.

Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. The use of elliptic curves in cryptography was suggested independently by Neal Koblitzand Victor S. Mi

ElGamal algorithm not only used for data encryption can be used for digital signatures, their safety depends on the calculation of a finite field discrete logarithm this problem. Key to the method. First of all, choose a prime number p, the two rando
