We describe a web based assessment system whose non-repudiation security feature is based on digital signatures. The first objective of this proposal is to enhance the students' understanding of the X.509/PKIX framework and digital signatures based on it. The second purpose is to develop a security enhanced web based assessment system, focusing on non-repudiation requirements. At the same time, this non-repudiation feature is used as a way for achieving the first objective. In this paper we describe the proposed system, the prototype we have already implemented as well as the results obtained in its evaluation by the students.
