# Multiplicative inverse modulo matlab

Modular multiplicative inverses in Matlab. I'm teaching a introductory cryptography and coding theory course this semester in which we're using Matlab to implement a bunch of different cryptosystems. There's actually a fairly pretty solution. GCD Greatest common divisor. [G,C,D] = GCD (A,B) also returns C and D so that G = A.*C + B.*D. Hermite transformations. Problem Modular multiplicative inverse. Modular multiplicative inverse is used for The Chinese Remainder Theorem and RSA algorithm. You can visit Wikipedia. Normal Modulus. X = M (mod Y) You can solve that with M = mod(X,Y) Inverse Modulus. Jul 12,  · Hello Professionals Can anyone help in how to write matlab code for following Compute the modular multiplicative inverse: a=1/b mod m. in cryptography. here b and m is known and a to be find.

# Multiplicative inverse modulo matlab

This can be done using gcd and mod functions as follows: A = ; M = ; [G, C, ~] = gcd(A,M); if G==1 % The inverse of a(mod b) exists only. I was a little surprised to see that Matlab doesn't have a built-in function (that I could find, at least) that computes in the inverse of x modulo n if it. The command “inv" in Matlab compute the inverse of a matrix over the product of inv(A)*det(A) and the multiplicative inverse of det(A) mod p. Modular multiplicative inverse is used for The Chinese Remainder Theorem and RSA algorithm. You can visit Wikipedia. Normal Modulus. X = M (mod Y). MULINV(X,P) is a function that finds the modular inverse of vector X over finite ( Galois) field of order P, i.e. if Y = MULINV(X,P) then (X*Y) mod P.

The command “inv" in Matlab compute the inverse of a matrix over the product of inv(A)*det(A) and the multiplicative inverse of det(A) mod p. I hope you mean the additive inverse, -mod, or the multiplicative Is there any way to calculate the inverse of the mod operator in Matlab or. Oct 26,  · the operations are done in modular arithmetic. One interesting result is that a residue. matrix has a multiplicative inverse if the determinant of the matrix has a multiplicative. inverse in Zn. In other words, a residue matrix has a multiplicative inverse if gcd. (det(A), n) = 1. Modular Multiplicative Inverse function in matlab. I have problem for calculate modular multiplicative inverse. example I have integer A = and M = mod Nov 28,  · is the modular inverses of X over P. The field order P must be a prime number and all elements of X should belong to the field i.e. X modular inverse of one is one and the modular inverse of zero doesn't customercaresinfo.comt Rating: Modular multiplicative inverse is used for The Chinese Remainder Theorem and RSA customercaresinfo.com can visit Wikipedia.. Normal Modulus. X = M (mod Y) You can solve that with M = mod(X,Y) Inverse Modulus. X.B = M (mod Y). Problem Modular multiplicative inverse.
