參數式列完備矩陣之轉加密方法

Abstract

拉丁矩陣是密碼學領域中，一個常用的數學型式，而列完備矩陣（Row-complete Matrix）是在Zn的拉丁矩陣的特殊形式。我們發現列完備矩陣，可以應用在雲端傳輸資料的轉加密（Re-encryption）系統中。本文中，我們探討更多列完備矩陣的屬性；並提出一個參數式列完備矩陣的轉加密方法，來加強雲端再加密系統的安全性。Latin matrix is one of mathematical type in the field of cryptography; in addition, Row-complete Matrix is a special form of Zn Latin matrix. The Row-complete Matrix can be used in clouds re-encryption system. In this paper, we discuss the properties of Row-complete Matrix; and propose a re-encryption method based on parameter Row-complete Matrix to strengthen the security of clouds re-encryption system.
