| 英文摘要 | In 16, Pass generalized the definition of zero knowledge proof and defined n(O(sigma(n)))-simulatable proof which can be simulated by a simulator in n(O(sigma(n))) time. Assuming the existence of one-way permutation secure against sub-exponential circuits and 2-round perfect hiding commitment scheme, an efficient 4-round perfect argument of knowledge was presented there. In this paper, we construct an efficient concurrent simulatable argument of knowledge under more general assumption. The new scheme is 5-round and is based on the existence of one-way permutation secure against sub-exponential circuits. However, for the scheme in 16, if using ordinary Sigma-protocol for the corresponding statement as sub-protocol, instead of Sigma-protocol with honest verifier perfect zero knowledge, the resulting protocol is not necessarily closed under concurrent composition. |
