本文提出基于区块链的凭证管理系统BCMS,结合RSA与DNA编码的改进双因子加密和增强认证,在不依赖大学管理机构的情况下实现凭证的安全存储、管理与恢复。

摘要:

大学教育在塑造个体的智力和职业发展方面发挥着关键作用,并对知识进步和社会发展作出重要贡献。通常,大学管理机构直接控制学生成绩的生成,并将凭证存储在其本地专用服务器中。因此,存在篡改凭证的可能性,同时也极有可能遭遇各种威胁和不同的安全攻击。为解决这些问题,我们提出了一种基于区块链的安全凭证管理系统(BCMS),用于在不涉及大学管理机构的情况下高效地存储、管理和恢复凭证。所提出的BCMS融合了一种改进的双因子加密(m2FE)技术,该技术结合了RSA密码系统和DNA编码,以确保凭证隐私,并为教师和学生提供了一种增强的认证方案。此外,为了减小密文凭证的大小及其转换时间,我们使用字符到整数(C2I)表代替ASCII表。最后,BCMS的实验结果和分析证明了其相对于现有技术工作的有效性。

英文摘要:

University education play a critical role in shaping intellectual and professional development of the individuals and contribute significantly to the advancement of knowledge and society. Generally, university authority has a direct control of students result making and stores the credential in their local dedicated server. So, there is chance to alter the credential and also have a very high possibility to encounter various threats and different security attacks. To resolve these, we propose a blockchain based secure credential management system (BCMS) for efficiently storing, managing and recovering credential without involving the university authority. The proposed BCMS incorporates a modified two factor encryption (m2FE) technique, a combination of RSA cryptosystem and a DNA encoding to ensure credential privacy and an enhanced authentication scheme for teachers and students. Besides, to reduce size of the cipher credential and its conversion time, we use character to integer (C2I) table instead of ASCII table. Finally, the experimental result and analysis of the BCMS illustrate the effectiveness over state of the art works.
