Webinverse is by using Extended Euclidean Algorithm. The details on the calcu-lations in gf(28) is best explained in the following example. Example Suppose we are working in gf(28) and we take the irreducible polynomial modulo m(p) to be p8 +p6 +p5 +p1 +p0. To calculate 8413, we need to go through several steps. WebExtended Euclidean Algorithm Given two integers a and b we need to often find other 2 integers s and t such that sxa+txb=gcd(a,b). The extended euclidean algorithm can calculate the gcd(a,b) and at the same time calculate the values of s and t. Steps: Initialize r1->a,r2->b. s1->1,s2-> t1->0,t2->

WebUse the Euclidean algorithm to compute gcd (a, b) = d. Determine whether d n. If not, then there are no solutions. Reformat the equations from the Euclidean algorithm. Using substitution, go through the steps of the Euclidean algorithm to find a solution to the equation ax i + by i = d. WebSep 18, 2010 · The extended Euclidean algorithm is particularly useful when a and b are coprime, since x is the modular multiplicative inverse of a modulo b. In this formula set a to e, b to (p-1)(q-1) and gcd(a, b) to 1 (because e and φ(pq) are required to be coprime in the RSA algorithm) and solve for x which gives you your d.
