RPC-MIX[1] guarantees the correctness of shuffle by opening the relationship of each input/output exclusively between the left-side and right-side server in one pair. There are two opening scheme:{\em probabilistic opening scheme} and the {\em fix opening scheme}. In the probabilistic opening scheme, for each input/output of the left-side, their relationship is opened with probability $p=1/2$ and in the fix opening scheme, the number of relationships being opened is fixed to the half of the number of inputs on both servers. Although the security of a Mix-Net should be analyzed based on robustness and anonymity, there is no such kind of rigorous analysis in [1]. In this paper, we define the robustness and anonymity of RPC-MIX and perform a rigorous security analysis on both opening schemes above. Our result shows that in a model where an adversary gains control over all servers, in order to guarantee security of RPC-MIX, we should adpopt the probabilistic opening scheme with $p=1/2$ with more than two pair of servers. |
