We present an approach for creating return codes for latticebased
electronic voting. For a voting system with four control components
and two rounds of communication our scheme results in a total
of 2.3MB of communication per voter, taking less than 1 s of computation.
Together with the shuffle and the decryption protocols by Aranha et
al. [1,2], the return codes presented can be used to build a post-quantum
secure cryptographic voting scheme.
