These standards offer many ECIES options, not always compatible, making it difficult to decide what parameters and cryptographic elements to use in a specific deployment scenario. In this work, we show that a secure and practical implementation of ECIES can only be compatible with two of the four previously mentioned standards. In addition to that, we provide the list of functions and options that must be used in such an implementation. Finally, we present the results obtained when testing this ECIES version implemented as a Java application, which allows us to produce some comments and remarks about the performance and feasibility of our proposed solution.

When a private or public document must be signed by a group of people, we call it multisignature scheme if all and every single member of the group signs the document.

The aim is to provide the students a better understanding of maths algorithms and basic concepts by using specific software, in a graduate-level course. In this paper we discuss how to structure, define, and implement a webbased course as a part of the traditional classes, according to the convergence of the European Higher Education Project. The proposed course facilitates the use of new Information and Communication Technologies.

The terms e-learning and b-learning are being overshadowed by u-learning (ubiquitous learning), since the learning scenario is any place and any device that can be used to get the materials. The task of preparing the appropriate materials in this new context cannot be addressed individually and, consequently, international collaborative process can be very fruitful. The main goal is to adapt the study materials for using in several Universities, with official recognition for any University involved in the collaborative process and with agreements with other Universities interested in the use of such materials. We will present an ongoing experience which involves the National Technological University (UTN) in Buenos Aires, Argentina, and Spanish universities: Salamanca University (USAL) and Pontificia Comillas University (UPCOMILLAS) in Madrid. The authors of this paper have updated a virtual Multivariable Calculus course, hosted in the virtual learning environment STUDIUM to be used by the students from the three universities.
