Abstract: Secure and auditable consolidation of results of an electoral process, in which local electoral authorities participate to validate local electoral results by generating a validation proof, which is communicated to a consolidation module that verifies that the validation proof has been generated by the appropriate electoral authorities and then generates a receiving proof, which contains the result of the validation, which could be the acceptance or non-acceptance of the validation proof. The receiving proof is finally sent to the electoral authorities. There are different ways of generating the validation and receiving proofs so as to be able to robustly verify the identity of the local electoral authorities who have participated in the validation of the electoral results and to verify if the validated local electoral results are the same that are going to be consolidated and to preserve integrity of the official records of the local electoral results.
