| Abstract: | 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。
The purpose of this study is to compare the equality of two secret values. Secure
multiparty computation in the previous study, usually through the protocol the
two sides, the one is announcer and the other one be told. The one be told by the
announcer who notified the results of verification, and the one be told only can
believe that the message. Through the semi-honest party can solve by the above
problems and reduce the computation required, but you can find a trusted third
party is not easy.
Based on the above problems, this study proposed in the framework of both the
secret of a new calculation of protocol, in this protocol the two parties (the one
is announcer, the other one be told) can calculate each have a secret are equal or
not. If different, this protocol does not leak any information about the secret
value. |
