In this paper, we examine the basic properties of n-th order linear feedback shift registers and show that n-th order shift registers based discrete logarithm problem is equivalent to discrete logarithm problem. This shows that the algebraic structure of n-th order linear feedback shift registers is useful in constructing cryptographic primitives.
