Let us assume that you have a message m and you will have to submit it several times to Alice using her public key. The only change you will have in these messages are the error vectors. You can then take all the sent messages and count how many times you had 1 in the first bit and how many 0. Since the error vectors are small, we can keep the bit that was used most times and thus remove the error bits. | |
