Mock voting can only detect malfunctions, not backdoors. Randomization of candidate ordering is a trivial challenge to overcome for a backdoored EVM. Don't fall for EC's PR.
Here is an example: Is NOTA ("None of the above") option's location also randomized? If not, a backdoor would listen for this sequence: NOTA, NOTA, NOTA, X, NOTA, NOTA, NOTA, X. And then it would start re-assigning votes in favor of X with say 60% probability. It doesn't matter where X is located. The backdoor might trigger only after a few 100's or 1000's votes have been given. How will mock voting or randomization help here?
The sad thing is that all these weaknesses have already been detailed in Hari Prasad's original paper. But EC continues to dish out the same flawed defense: https://indiaevm.org/evm_tr2010-jul29.pdf https://indiaevm.org/evm_tr2010-jul29.pdf
