A New Key Agreement Scheme Based On A Well-Known Property Of Powers

Michele Fabbrini

Abstract

In this paper I propose a new key agreement scheme applying a well-known property of powers to a particular couple of elements of the cyclic group generated by a primitive root of a prime p. The model, whose security relies on the difficulty of computing discrete logarithms when p is a “safe prime”, consists of a five-step process providing explicit key authentication.
