We show the following: (i) In existing anonymous credential revocation systems, the revocation authority can link the transactions of any user in a subset T of users in O(log vertical bar T vertical bar) fake failed sessions. (ii) A concern about the DLREP-I anonymous credentials system described in [1] and [2].
