| dc.description.abstract (摘要) | 本研究的研究目的是比較雙方秘密數值是否相等，而在以往的安全多方計算的研究，通常雙方的秘密數值經過協定之後，一個為告知方，另外一個為被告知方，由告知方通知計算後之結果，而被告知方只能相信此訊息。如果藉由半誠實的第三方可解決上述問題並減少計算量，但找到可以信任的第三方是比較不容易的。基於以上問題，本研究提出一新的秘密計算協定，在此協定下參與的雙方(告知方、被告知方)可以算出彼此所擁有的秘密是否相同。如果不同，此協定不會洩漏任何秘密值的資訊。本方案亦提供驗證機制，讓被告知方能驗證告知方是否屬實。 | zh_TW |
| dc.description.abstract (摘要) | The purpose of this study is to compare the equality of two secret values. Securemultiparty computation in the previous study, usually through the protocol thetwo sides, the one is announcer and the other one be told. The one be told by theannouncer who notified the results of verification, and the one be told only canbelieve that the message. Through the semi-honest party can solve by the aboveproblems and reduce the computation required, but you can find a trusted thirdparty is not easy.Based on the above problems, this study proposed in the framework of both thesecret of a new calculation of protocol, in this protocol the two parties (the oneis announcer, the other one be told) can calculate each have a secret are equal ornot. If different, this protocol does not leak any information about the secretvalue. | en_US |
