On application of discrete logarithms in information-hiding and knapsack problem with new properties of Sk-Sets

الملخص EN

Discrete logarithms are applied ٨؛ many cryptographic problems .كه'ما instance , in ^ء؛1طاا key , and for construction (١١■ sets with distinet sums of k-elements.

The purpose of this paper is to modify the method of information-hiding using disercte logarithms ء introduce new properties of Sk - sets , uscdthe direct product ٠٤* groups to construct cyclic group and finally, present modified method for knapsack problem using each of disercte logarithms and ،؟*-sets.
