We need to know how hard it is to reverse the exponentiation 我们需要知道求幂运算的逆运算的难度。
When more than one exponentiation is performed in a single expression , the 如果在单个表达式中执行多个求幂运算,则按
Exponentiation uses the 求幂使用
If we use exponentiation to encrypt or decrypt , the adversary can use logarithm to attack 如果我们运用求幂运算来加密和解密,对手就可以运用对数进行攻击。
First , computers have circuits for performing arithmetic operations , such as : addition , subtraction , division , multiplication and exponentiation 第一,计算机具有进行加、减、乘、除及取幂等各种算术运算的电路。
