2的16次幂正整数d与n，编写计算d-1 (mod n) 的程序； 2、对于三个不超过2的16次幂正整数a、e与n，编写计算ae (mod n) 的程序。 在上述程序基础上写出下列程序： （1） 对给定的10000以内数判定其是否为素数； （2） 进行ElGamal体制的加密与签名。 -two of 16 power-positive integer d and n, calculate the preparation of d-1 (mod n); 2. For not more than 2 3 16 Powers positive integers a, e and n, calculate the preparation ae (mod n) procedures. In the above procedure to write on the basis of the following procedures : (a) the right to 10,000 within a few judging whether a prime number; (2) ElGamal encryption and signature.

硬件求解平方根源代码加密 (硬件求解平方根的，将license添加到原有的MaxplusII或QuartusII的license中就可以直接使用，但源代码加密。altera提供 )-solving square root of the hardware encryption code (square root of the hardware solution will be added to the original license MaxplusII or Quartus II of the license which can be directly used, but the source code encryption. ALTERA provide)
