Supervising Secret-Key Agreements in a Level-Based Hierarchy
A key agreement protocol is utilized in a network system such that two users are able to establish a commonly shared secret key. Entities within the same security level can commun...

A New Baby-Step Giant-Step Algorithm and Some Applications to Cryptanalysis
We describe a new variant of the well known Baby-Step Giant-Step algorithm in the case of some discrete logarithms with a special structure. More precisely, we focus on discrete lo...

Analysis of the GHS Weil Descent Attack on the ECDLP over Characteristic Two Finite Fields of Composite Degree
In this paper, the authors analyze the Gaudry–Hess–Smart (GHS) Weil descent attack on the elliptic curve discrete logarithm problem (ECDLP) for elliptic curves defined over c...

The Function Field Sieve in the Medium Prime Case
In this paper, we study the application of the function field sieve algorithm for computing discrete logarithms over finite fields of the form Fqn when q is a medium-sized prime po...
