中文摘要 | 在此篇論文中,我們利用不可超越寫入-讀出法定人數集合結構(nondominated write-read coterie)來實現秘密分享技術(secret sharing scheme)。一個秘密分享技術必須滿足秘密重建(reconstruction)特性及完美(perfect)特性,我們將證明利用不可超越寫入-讀出法團產生的存取結構(access structure),可以滿足上述之秘密分享技術的二個特性。我們並將所提的技術與一些以法定人數集合系統(quorum system)為基礎的方法加以比較,如同我們於論文中指出的,因為寫入-讀出法團比法定人數集合系統更具一般性,這使得我們所提出的秘密分享技術更具有彈性,能夠達成更低的通訊成本(communication cost)及更高的擷取度(availability)。 |
英文摘要 | In this paper, we utilize nondominated write-read coteries to implement a secret sharing scheme. A secret sharing scheme must satisfy (1) the reconstruction property and (2) the perfect property. We will prove that the access structure derived from a nondominated write-read coterie can satisfy the above-mentioned properties of the secret sharing scheme. We also compare our scheme with the ones utilizing quorum systems. As we will show, our scheme is more flexible than related ones since write-read coteries are more general than quorum systems. Thus, our scheme can achieve lower communication cost and higher availability. |
