中文摘要 | 檢查與確認欺騙者之方法為秘密分享策略中一個重要的問題。本文探討(t,n)秘 密分享策略中欺騙者之檢查與確認技術,作者提出一種安全的秘密資訊檢查方法,藉此方法 可輕易地確認欺騙者;且本方法使用者所需之秘密檢查資訊較少。以此方法為基礎,本文更 提出一種能確認欺騙者且能分享多個秘密之秘密分享策略,本方法不僅安全且所需之秘密檢 查資訊非常少。 |
英文摘要 | In this paper we discuss the cheating problems of the (t,n) secret sharing scheme. An unconditionally secure information checking protocol is proposed, in which cheaters can be detected and identified. Moreover, a lesser amount of secret information is required for each participant. Based on this protocol, we proposed a multistage secret sharing scheme with cheater identification (MSSC sheme), in which the secret information is drastically reduced by the adroit use of a one-way function. The scheme is secure and practical. |
