English Abstract

A Diophantine equation is an indeterminate polynomial equation that allows the variables to be integers only.

A linear Diophantine equation of the form ax + by = c has solutions if and only if gcd(a, b) | c.

There is a similar result for linear Diophantine equations in more than 2 variables.

We present a new Public-Key cryptosystem for thissystem; the equation ∑_(i=1)^n▒〖a_i x_i 〗=C is solved modulo m, in which C and a_iare known and x_i∈ {0, 1, 2}.

It can be simply seen that in general case we need to investigate 2^n combinations, while in our system, one need to examine 3^ncombinations which means that the security of the new system is higher than that ofMerkle’s.

Moreover in this thesis we propose an efficient multivariate public key cryptosystem based on permutation p-polynomials over finite fields.

We first characterize a class of permutation p-polynomials over finite fields F_(q^m ) and then construct a trapdoor function using this class of permutation p-polynomials
