A method of security and verifiability of an electronic vote, comprising reception of a temporary voting ballot, during which a temporary voting ballot is received by a voting entity, the temporary voting ballot being encrypted by a public voting encryption key; reception of a validation voting ballot, during which a validation voting ballot is received from the voting entity, the validation voting ballot being encrypted by a public validation encryption key; decrypting the validation voting ballot by a private validation key associated with the public validation encryption key; validating a validation request generated from the decrypted validation voting ballot sent to the voting entity; the preceding steps being repeated until the acceptance of the validation request by the voting entity, after which the encrypted temporary voting ballot is registered as a definitive voting ballot awaiting its counting.
