Abstract
e-Cognocracy is a new, creative, innovative and cognitive democratic system based on the evolution of living systems which focuses on the extraction and social diffusion of the knowledge derived from the scientific resolution of highly complex problems associated with public decision making related to the governance of society. Among the many tools needed to fully develop e-cognocracy, we will focus in e-voting, as it is the first needed to gather the information supplied by the citizens.
One of the things that may drive people away from this kind of systems is their complexity. In this paper we present an e-voting protocol designed to work with e-cognocracy, much simpler than the previously existing one [1], through the use of short linkable ring signatures.
Short linkable ring signatures are a cryptographic primitive that allows one person to sign as a member of a group, but without giving any information about the identity of the signer and with no previous set up and, furthermore, all the signatures from the same signer can be linked together but keeping the anonymity. The key element they present is that, unlike other schemas, they have a constant size (making them independent of the number of people in the group).
