Two solutions for this to my mind. (1) Give voters a paper receipt like they get at an ATM. They can confirm their vote, leave the receipt, and the paper trail is there for anyone to recount. It would be extremely complicated to tamper with both the electronic and paper ballots and have the results come out the same. (2) Improve the science of exit polling. Right now exit polls suck due to sampling biases and the inability of independent firms to cover enough territory [1], but this kind of independent verification--if done expansively and competently--could provide an independent verification on the final vote tallies. If the tallies drastically differ from the exit polls, then an investigation is warranted.
