WebIn this module, we will cover the square-and-multiply method, Eulier's Totient Theorem and Function, and demonstrate the use of discrete logarithms. After completing this module you will be able to understand some of the fundamental math requirement for cryptographic algorithms. You will also have a working knowledge of some of their applications.
Square-and-Multiply - Modular Exponentiation Coursera
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. Especially in cryptography, it is useful to compute powers in a ring of integers modulo q. … See more WebIn this “Babylonian” method, we a start with an arbitrary positive number x0 , and then apply the By subtracting x from both sides, we conclude that x = . x2 following iterative process: Multiplying both sides of this equality by x, we get a = x ; µ ¶ this is exactly the defining equation of the square root. 1 a xn+1 = · xn + . only ms word 2010 free download
