In the last years, the use of Information Technologies in the daily life has grown significantly. Activities as article downloading or bank account management can be made from any place using Internet. An application with a promising future of these technologies is its use for the electronic vote, so that a person can, from any site, to vote and to participate in the democracy with guarantees. On the other hand, this great flow of information has favored the free circulation of programs and source code, having generated a set of tools that can be used in a different way from the traditional software tools, giving to the users more freedom at the time of having them. Nevertheless, along with all these advantages, the popularization of the new technologies has also brought certain disadvantages. Given the great amount of information (sensible in many cases) that actually flows through computer networks, the number of computer crimes has grown and also does the users’ distrust on the reliability of these technologies. This project tries to develop a system for securization of communications, following the philosophy of free software, for electronic vote applications offering a high reliability and security required by these systems.
