Security is one of the main problems in Web-based assessment systems, particularly in guaranteeing the non-repudiation of test submissions. The authors have developed EVAWEB, a Web-based assessment system that addresses this issue by using digital signatures. Moreover, the use of this technology in EVAWEB provides a real context to students for learning how digital signatures work. This article focuses on the enhancements that have been incorporated into EVAWEB in order to develop an improved second version of the system.
