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.

Category / Keywords: public-key cryptography / public-key cryptography, key agreement scheme, discrete logarithm problem, implicit key authentication, explicit key authentication
