| 英文摘要 | In this paper we study the possibility of reducing the setup assumptions under which concurrent non-malleable zero knowledge protocol can be realized. A natural model choice is the bare public-key (BPK) model of 6, a model with very minimal setup assumptions. Our main contribution is to show in this model the following about constant-round concurrent non-malleable black-box zero-knowledge arguments. - They can be constructed from any one-way function for any language in NP. Here, our construction takes 5 rounds, and we can reduce it to a round (round-optimal) argument under existence of one-way permutations. - Under number-theoretic assumptions, they admit a time-efficient instantiation for some specific NP languages (e.g., all languages having efficient Sigma protocols, for which we can implement our construction using only O(1) modular exponentiations). Compared to the non-black-box construct ion in a concurrent work of OPV, ICALP 2008 in this model, our protocol (even the construction from one-way function) is significantly more time- and round-efficient and can be based on more general assumptions. |
