摘要
通过对Y.Mu等提出的3组从n条消息中获取m条不经意传输协议的分析,指出了协议的不安全因素,并分别做了改进,防止了用户得到更多的消息或不遵循协议,其中对"Betterm-nOT"的改进方案比Y.Mu等提出的所有方案效率都高.
We analyze the security of the three m out of n oblivious transfer schemes proposed by Y. Mu et al, and then point out the insecurities of their schemes. We also provide our improvements on them respectively, which prevent users from getting more messages or disobeying the protocol. One of the improved schemes is more efficient than all the schemes proposed by Y. Mu et al.
