Today voting processes are the most important element of democracy as the societies way to make decisions. Such processes have been influenced by information technologies until becoming be named electronic voting. This topic has been an active research area, on which, cryptographic primitives are used in order to propose secure protocols. Most of them use a Public Key Infrastructure. In this paper, we propose the use of Bilinear Pairings, first implementation of Identity Based Cryptography, in order to provide stronger security requirements than protocols based on Public Key Infastructure and without requiring the entire infrastructure needed by them. We make a comparative analysis of our proposal with previous proposals, which is based on the total number of needed key pairs and required authorities by those protocols.
