Note also that subtraction and division fail many of our laws, … In mathematics and computer programming, exponentiating by squaring is a general method for fast computation of large positive integer powers of a number, or more generally of an element of a semigroup, like a polynomial or a square matrix. Some variants are commonly referred to as square-and-multiply … See more Recursive version The method is based on the observation that, for any integer $${\displaystyle n>0}$$, one has: If the exponent is zero then the answer is 1 and if the exponent … See more This method is an efficient variant of the 2 -ary method. For example, to calculate the exponent 398, which has binary expansion (110 001 110)2, we … See more There are several methods which can be employed to calculate x when the base is fixed and the exponent varies. As one can see, See more A brief analysis shows that such an algorithm uses $${\displaystyle \lfloor \log _{2}n\rfloor }$$ squarings and at most Each squaring … See more This algorithm calculates the value of x after expanding the exponent in base 2 . It was first proposed by Brauer in 1939. In the algorithm below we make use of the following function … See more Many algorithms for exponentiation do not provide defence against side-channel attacks. Namely, an attacker observing the sequence of … See more The same idea allows fast computation of large exponents modulo a number.
