| 英文摘要 | In this paper we break a knapsack based two-lock cryptosystem proposed at icics'03 [7]. the two-lock cryptosystem is a commutative encryption algorithm that is very useful for the construction of the general t-out-of-n oblivious transfers and millionaire protocol. however, our analysis shows that the proposed knapsack based two-lock cryptosystem is extremely insecure. the serious flaw is that the sender in the two-lock cryptosystem can retrieve the secret key of the receiver fairly easily. we have implemented the attack on a pentium 4 2.5 ghz processor. for the parameters given in [7], it takes only several minutes to break that knapsack based two-lock cryptosystem. |
