　　本論文介紹了區(qū)塊鏈的基本原理,重點是其在教育領域的潛在應用。本論文解釋了這項新技術如何既可以重塑制度規(guī)范,又可以使學習者增強對信息安全的重視。提出了主要概念,回顧了包括教育在內的不同研究領域的區(qū)塊鏈技術和智能合約應用文獻。本論文的創(chuàng)新點是:a)根據(jù)當前技術發(fā)展和現(xiàn)狀,提出在教育環(huán)境中應用區(qū)塊鏈的方案,盡管基于區(qū)塊鏈的產(chǎn)品在教育中的應用仍處于起步階段;b)在對包含各種敏感數(shù)據(jù)的大學網(wǎng)絡的安全性保證的區(qū)塊鏈技術實用性的數(shù)值分析中,即學生和員工的生物特征數(shù)據(jù)或健康記錄;并通過對此類參數(shù)的標準化評估來比較普通方法和區(qū)塊鏈方法的安全性參數(shù)。本論文提出了私有區(qū)塊鏈框架在大學網(wǎng)絡中的應用,為了提高其信息安全水平。私有區(qū)塊鏈技術是從大學網(wǎng)絡信息安全通用方法向新技術邁出的一步,該新技術為利用以太坊區(qū)塊鏈技術的網(wǎng)絡之間的記錄和信任帶來了高度的可審計性和不變性。此外,還涵蓋了專用以太坊網(wǎng)絡相對于主要公共以太坊網(wǎng)絡的主要優(yōu)勢。從統(tǒng)一安全標準的角度對建議的私有區(qū)塊鏈系統(tǒng)的安全參數(shù)進行了分析,以實現(xiàn)方法的客觀安全級別比較。觀察了各種安全級別評估方法。這部分的主要貢獻在于利用全球采用的標準ISO/IEC 15804...
