In some mix networks, a special tag is attached to the messages or inputs and acts as an input to the verification function. A tag to a message or input can only be produced by its owning user and may be a signature [25, 84] or a MAC [62]. This type of mix network is denoted as TMN (with tag). While the tags may be helpful for efficient verification of shuffling validity, there are two concerns in TMN. 1. Distribution of the keys for signature or MAC causes additional computation and communication.

4) Otherwise, for any (t1 , t2 , . . , tv−1 , tv+1 , . . , tn ), there is at most one tv to n n satisfy logg1 i=1 yiti = logy i=1 ziti . This implies that among the 2nL possible choices for (t1 , t2 , . . , tn ) (combination of 2(n−1)L possible choices for (t1 , t2 , . . , tv−1 , tv+1 , . . , in [52]). ✐ ✐ ✐ ✐ ✐ ✐ “K13841” — 2014/3/4 — 15:45 ✐ 34 ✐ Anonymous Communication Networks: Protecting Privacy on the Web n n most 2(n−1)L choices to satisfy logg1 i=1 yiti = logy i=1 ziti , which is a contradiction to the assumption that P r [ t1 , t2 , .

D(cn ) is a negligible concrete probability. To prove Theorem 2, a lemma is proved first. Lemma 2 Suppose yi , zi ∈ G1 for i = 1, 2, . . , n. Let ti for i = 1, 2, . . , n be random integers such that ti < 2L . If P r [ t1 , t2 , . . , tn ∈ {0, 1, . . , 2L − 1} | logg1 ni=1 yiti = logy ni=1 ziti ] > 2−L , then logg1 yi = logy zi for i = 1, 2, . . , n. Proof: P r [ t1 , t2 , . . , tn ∈ {0, 1, . . , 2L − 1} | logg1 ni=1 yiti = n logy i=1 ziti ] > 2−L implies that for any given integer v in {1, 2, .
